This fourth instalment in the Kitty Katt series delivers just as much action as the previous books, proving that a newborn can't slow Kitty down. Fighting another grand mastermind design full of red herrings and unknown enemies, Kitty and her alien husband Jeff Martini are on hand to save the day.

To recap for those who aren't familiar with the series, Kitty inadvertently discovered that there are aliens on Earth - very sexy, drop-dead gorgeous aliens who came here from their own planet in the Al

The Kitty Katt series has reluctantly become one of my favorites. Though written in the style of a humorous urban fantasy, this series is sci-fi all the way (though thankfully, it's dispensed with most of the incomprehensible technical jargon after the first book). While I'm not really a sci-fi girl, it was actually the humor that turned me off initially. Kitty was too sarcastic, the A-C's were too unbelievable, and the plot elements were insanely over-the-top. Kitty and Martini were too instant ...more

Such much ridiculousness going on here, but I can't get enough of it.

Kitty is now known as Wolverine with Boobs and still lusts for Martini like a sailor on leave.

Total wackiness ensues.

Dieses Buch beginnt für Kitty nicht ganz so rasant, wie der Leser es gewohnt ist. Das ist natürlich auch besser so, denn schließlich ist sie schwanger. Trotzdem fand ich es etwas schade, dass sie sich auf Grund des Kindes zurückhalten musste. Es war natürlich eine logische Sache, aber ich war zu dem Zeitpunkt ein wenig pessimistisch, ob es eine gute Idee war, so früh in der Reihe bereits ein Kind für Jeff und Kitty in die Handlung hineinzubringen.

These books are insane. I think Gini took everything she liked, mixed it together, went a bit crazy, wrote it down and made a freaking marvelous books. I think all authors should just run with it like she does. But then I am sure if someone else did it, I would think "come one, please", but here, here it works.

What to say then, I am a bit lost for words. Ok, I will try to put my mind back together. Kitty is awesome as always, I really need her as my bff. She kicks ass and saves the day. Martini,

*Contains MINOR SPOILERS for the previous books in the series.

There is doubting it, Gini Koch can write the heck out of a book. Funny one-liners, incredible action and let’s not forget the amazingly compeling and lovable characters. The Katherine “Kitty” Katt series is right up there amongst my favorite series ever, if not at the top and am not surprised at all that Gini has done it again with Alien Proliferation.

Loved this book so much. There was so much happening this time around and a lot at stake.

It's great to feel so many emotions about every single character, it's intriguing how every little character can be important in some way and really make you care about them.

I don't think I've ever read a series that makes me actually laugh out loud so much while reading, this can be embarrassing if it happens at work but

Following the events of ‘Alien in the Family’, Katherine “Kitty” Katt is now officially Mrs Jeff Katt-Martini, and enjoying wedded bliss to her Alpha alien honey. But hot on the heels of Jeff and Kitty’s nuptials was more joyful news of a baby on the way.

With baby and baby shower looming, Kitty is holed up on bed rest and hating every minute of it. Carrying an alien baby means Kitty’s breasts are turning to torpedoes and baby’s kicks are rocket-powered.

Kitty also hates having to take to bed wh
I enjoyed this book as I have all the books, because of the snark and verbal humor. I also enjoy Kitty's effortless ability to lead all the alien/human teams involved. This one got considerably more serious in many ways, and tied in some loose ends from earlier books that clearly were deliberately left unfinished for this book. It really was in many ways an excellent addition to the series, and would have earned 4 stars except for the end when the author virtually restarted the series from scrat ...more

Gini Koch does it again; her Katherine “Kitty” Katt series is filled with so much action, unbelievably fantastic characters, action that will keep you on your toes and romance that always makes a girl need to fan herself.

Kitty is ready to have her baby, not without complications of course. (I wish she remembered all that stuff but neither did Reader). Jamie is quite special and shows it from the start. While still in recovery Kitty uncovers some serious issues with Christopher that lead them into yet another conspiracy within a conspiracy which also happens to include one of her childhood friends, Amy. All the women seem to be pregnant and therefore out of commission for field work and Kitty is chomping at the b ...more

Four books into the Katherine "Kitty" Katt series and Koch is still going strong.

Once more Koch delivers a wacky, action packed, delightfully fun adventure that keeps you guessing and laughing from the start.

There's quite some emotional moments in this book as well with at least two moments that had us sniffling.

Kitty's adventures have always been a bit over the top (which to me is one of the charms of this series), but in this book certain events sky-rocket totally out of there, to soar back in

I have to admit that I didn’t like "Alien proliferation" as much as the other three books. Don’t get me wrong, it is still an excellent read, but while I thought that first three books in the series were flawless, I could pinpoint some minor minuses in this one.
The first quarter of the book was kind of slow because of Kitty’s pregnancy. But what upseted me the most was that Kitty wasn’t her sharp self. I love this heroine because of her brain, because she gets everything better and faster than a

Any of you who have read reviews of mine previously know two things: I hate trying to write a plot synopsis, and I despise spoilers and the people who disseminate them. If you're reading this review to get either of those things, all I can tell you is that you need to buy this book, read it, enjoy it, and recommend it to all of your friends. OK, you can go now. There's nothing more here for you.

Alien Proliferation picks up the story several months after the ending of Alien in the Family with Kitty heavily pregnant and about to give birth to her first child. Being pregnant with an alien / human hybrid has really taken it out of our heroine though so she is stuck on bed rest and feeling rather cranky, luckily she has superdad-to-be and empath Jeff on hand to anticipate her every need. The bad guys aren't going to wait until after the happy event to start causing trouble though and things ...more

*SPOILERS for books 1-3*

As Alien Proliferation opens, Katherine "Kitty" Katt (now Martini) is nearing the end of her pregnancy, and she's miserable: bed rest, inability to decide on even the smallest baby supplies, and discomfort all combine to make Kitty one cranky agent.

Then, a phone call comes in - Kitty's best friend from college is in trouble. Jeff and Christopher rush out to save the day, but of course it's not that easy: more problems are uncovered than are solved, and then suddenly - the
I was pretty disappointed with this installment 2.5 stars. I think there are too many characters now, which when added to the too many crazy plots, is just too much all around. It starts to read like a first grader is telling you about something that happened to them.
We did this. He did this. Then we all went here. Then person x opened the door. Then persons y and z walked through it. He tripped and fell. Then we all laughed. Then person x.... Anyway you get my point. It was a like a play by p
3.5 stars.

Some parts really dragged on, and I definitely took notice of Kitty's ego this time around. It got a bit annoying. There were also a few parts in the book that were really slow, when everyone was talking and Kitty basically had to explain everything to all these really smart guys. So it was slow and a bit unbelievable.
Still, though, I found myself liking the action, and Jamie is one interesting baby!
Kitty's getting to be too much for me. She has a baby, nearly dies, (not a spoiler, it's in the blurb) and when everyone is showing concern she just blows them off. She hasn't really matured at all over the series, she's still like a squirrel on crack. It was amusing at first, but it's getting old, especially since she's a mother now. But what has really killed it for me is the fact that she claims to have not one, but two soulmates, neither of which are her husband. I get it, different world, a ...more

This series is a lot of fun to read. Quick in pacing, exciting and non-stop from start to finish. This book was no exception. It was some of the content that just really drove me insane this time. Like Kitty, I'm a new mother and I guess some of the preposterous insanity (which is always there) just bugged me. The ease in which she goes from giving birth to pumping gallons of breast milk to galavanting around Paris sans recently born child. Also the constant constant constant reference to the "t ...more

I could not finish this book. I got to page 86 and I was so not into this book at all. There are all these aside jokes, and "girlfriend" from any gay that happens to be nearby, and after dying twice during childbirth, she'd rather talk about music she likes than push. Finally everyone around yells, "Push!". Okay, what in the hell. This is like slapdash comedy, not the new version the 100 years ago version.

I thought maybe it got better at the end but no, it's Kitty standing in front of everyone

For some reason, I just love this series. Slightly corny, action packed, Men-in-Black meets Lara Croft (character, not profession).

Kitty and Jeff (alien hottie) are now married and here comes the baby. As usual, there's no time for laying back and enjoying the new family as bad guys are out to get all of the Alphas and take over (of course).

Armed with her handy dandy iPod and newly formed powers, Kitty's not going to sit back on maternity leave. Oh, no. She ends up in the middle of it all, and
And once again Gini Koch did not disappoint: the breaak-neck action and witty banter are all back just like the yummy A-Cs and cutie Poofs. As usual so many things happened in a whirlwind you have to hang on not to get lost as not just the A-Cs but Kitty, the mysteries and everything happens like at hurricane-speed. Fantastic new addition to the series, loved it and as always: can't wait for more! :-D

I gave this book 4 stars instead of 5 for reasons that others might not find to important. The story was great, I was entertained just like all the others and kept on the edge of my seat. I was disappointed in the author's lack of knowledge of some mothering facts. 1) it IS possible and quite acceptable to breastfeed past the time an infant starts getting teeth. I've done it, three times. 2) co-sleeping is not always a bad thing. Yes it should be done safely but a parent should never be told the ...more

I've enjoyed all of Gini Koch's Alien series--and there's more danger, suspense, and nasty villains in this episode--and all while Kitty Katt has a baby shower and a baby and copes with being a mother. And she is a mother; she has to feed and take care of the baby. And the action is non-stop!

I love the dialogue, the characters, and the poofs. Oh, and Ace--and I've probably missed some. I enjoy Jeff's roar ratings; he goes from "rabid dog" past "enraged bear" and on to "lion takes over the veldt.

So I started reading this series trying to find "something different". I thought the first book was good. Not great but good and made me want to continue the series. I must say this is WAY far from my normal books (Dresden, Iron Druid, etc) but I gave it a try. After the first book it started to drag a little and didn't really pick up until this book. I think the author really has the base down on the characters and it took the first three to really solidify that. If you've stuck with the books ...more

It's not exactly hard for me to explain why I finished this book in about three days. I think it's a combination of my recent life experiences with motherhood and, in general, life's uncertainty that I share with the main character. The story was so propelling for me that I literally could not put the book down. It's also pretty clear that this book is intended to set up the next part of Kitty's life as part of the A-C community. There was a little less action and a little more mystery but, over ...more
As Alien Proliferation begins, Kitty is about-to-pop pregnant. During a meeting with Chuckie, head of the CIA's ET division, and some higher ups Kitty gets the niggling feeling that something's off. Before she has much time to worry about it the baby is coming.

With all books in this series, there's a lot of action, snarky humor, and jealousy issues. There was, however, several more solemn moments in this installment. So much of this series is waaaay out there that it was nice albeit surprising

More of a 3.5.

I confess that this one didn't work well with me. Oh, it had parts that worked pretty darned well but... I think the biggest problem I may have had was the timeline. If I'm to understand correctly, this took place over about a week. The baby was born on Christmas. They finally slept and woke up on New Years. Right. See, I have a lot of issues with that one, like the fact that there are no indications of passage of DAYS. And since we don't know how many days passed while Kitty was t
