Offered the choice between guarding a clone, or remaining stuck in her office, Sam accepts the former, even though she suspects Stephan is using her as bait to draw out the dangerous Sethanon.

Let me get out the positive out there: first of all, this series is action packed, there is never a dull moment and lots of authors need to take notes on how to set up a storyline and how to write clues and reveals.
Secondly, there is no unnnecessary whining, pining, being stupid (well... Gabriel can be dense at times) but really, there is not a lot of eye rolling at the characters' actions.
Thidly, there is romance, just how I like it. It's there, it's not rushed and it's not overpowering the s

OMG!!!!!! WHYYYYYYYYYYYYYY!!!!!!! This is soooo good, the ending left me NEEDING AND WANTING more! The war hasn't even started yet, what is going to happen? Where is it all going to go? Are Gabriel and Sam actually going to be together? Are they mates? How will this resolve?????

This is what I'm left feeling after finishing book 3! Arthur had plans to make this series a 4 book series, but Riley got in the way! DAMN YOU RILEY!!!! *shakes fist* this is such a great series and I'm salivating for mo

Why in the name of all that is holy would a publisher re-release a book series that has no ending? It wasn't until after I read Memory Zero that I realized these books had been previously published. That wasn't a problem for me, but when I started reading other reviews, I found out that Keri Arthur had abandoned the series after book 3. Surely, it wouldn't be left unresolved... would it? Yes. It would. I reached out to the author on Twitter and asked if what I heard was true. She told me she wro ...more
The publisher got Arthur to write a five page epilogue to append to the end of this book to try and make it seem like the re-issuing of the first three book of this unfinished series wasn't a terrible idea. It's a big load of... It was a promising series that was never finished and ends abruptly. Adding a few pages that try to make it seem like there's suddenly a guaranteed happy ending in store for the couple that was refreshingly taking a slow path toward a relationship just doesn't solve the ...more

My English review

I was very eager to get into this third novel after finishing the second. I must say that this is the last volume the author wrote for the series and I was very curious to know the answers to my questions, including about the Sam’s past.

After the latest events and realizing that she is not happy and even more alone than ever, Sam decides to apply for a transfer. Yet it seems that Stephan does not agree with her, and offers her one last mission instead, solo,
So, I Read This Book Today
Great series ended too soon by publisher I spent my birthday with a new series (for me) that I was really enjoying. The Spook Squad by Keri Arthur. The premise and story are fascinating, involving a close-to-us parallel world where nonhumans live alongside normal in an uneasy balance. They are policed by the SIU, a shadowy group set up to police nonhumans.The main character in the book is Sam Ryan, a State Police Officer. As far as Sam is concerned, she is fully human - but is she truly? With no ...more
Agent Sam Ryan has had enough. She wants out, and she wants out now. She's sick of putting up with Gabriel's crappy attitude, sick of seeing nothing but paperwork and the inside off her small office. But most of all, she is sick of feeling lonely. It's time to take control and get a life outside of work. But Stephan, the man in charge of the SIU, isn't about to let her go easily. Offered the choice between guarding a clone and probable enemy of the country, or remaining stuck in her shoe box, Sa ...more

PENUMBRA continues the quick pacing and action of the previous two books in this series. I liked figuring out just exactly what Sam is and how she fits into the vast network of government clones running amok around the world. I loved discovering Sam's powers along with her and how she learns about them was fascinating. This series storyline with an almost never ending rabbit hole of discoveries about just what the government has been doing in regards to

Sam has had enough of Gabriel pushing her away and not letting her get involved in any of their cases - she is sick of being stuck in her tiny office doing paperwork so demands a transfer from her boss Stephan. Stephan doesn't want her to leave so he offers to let her guard Wetherton, a politician who they know was replaced by a clone.

Gabriel is relieved when he realises that Sam is no longer his partner - until he finds out her new assignment. He believes that she will be in danger and is dete

I actually don't mind the unfinished bigger story arc. In a sense, the confrontation in the last chapter makes for all kinds of possibilities with Josh/Joe.

The epilogue also gave a hint to Sam & Gabriel's future, probably not as romantic as I would have liked but still pretty ok.

I'd highly recommend this series to anyone who wants to read an urban fantasy series that doesn't have too many books.

I am sad too see this series end. especially seeing as it ended on such a cliffhanger and on the whole I am not happy with how the series was finished. The whole point of the books was to find out the truth about Sam, this is achieved, right at the end of the book. However, it is not resolved, there is no real sense of closure. The way this book ends, makes it feel like there will be another book in the series, when as far as I know, this is not the case.

I am really torn in trying to rate this book. I enjoyed it - a lot. Enough that I'd like to go back and read the first books in the series, except for the fact that the ending SUCKS. I have one criteria for anything I read: the book must have a good ending. This doesn't.

As for what hooked me on the book, Keri Arthur wrote an action-filled, fun book to read. The characters seem real and the reader will like them. Really - it's the ending that kills this book.

So how do I rate this? ARGH. I give

Lock the doors and take the phone off the hook, you will not want to be interrupted for this! You’ll never view a storm the same way, not once you’ve been electrified by Samantha Ryan.

The elusive Joshua comes into focus as we are lead further down Sam’s dark past. Keri Arthur again proves herself to be a twisty turny author as we are lead down on path, only to suddenly find ourselves facing the wrong way in the wrong time zone!

So I do love Keri Arthur, one of these days I am going to get around to reviewing all the books by her that I have read, but needless to say she is one of my go to authors when I am looking for a familiar urban fantasy, she's just one of those people I can count on to write an enjoyable book. I enjoyed the second book in this series, so I figured I was going to enjoy this book just as much. Truth is, for the most p

Agent Sam Ryan wants out of the Special Investigations Unit. She’s sick of the attitude from her partner, Gabriel Stern. She’s sick of the paperwork. Most of all, she’s sick of feeling lonely. But her boss isn’t about to let her go that easily. He gives Sam a choice: either stay stuck in her office or guard a clone replacement of Dan Wetherton, a government minister. Sam reluctantly chooses the latter—even though she suspects she’s being used as bait to draw out the SIU’s elusive nemesis.

Sam is tired of Gabriel’s attitude and reluctantly chooses a guarding assignment and even though they are on separate cases they still cross paths at every turn and soon discover that the connection between them is far more powerful than any could have imagined in thrilling urban fantasy.

Thrilling suspense and action keeps readers on the edge of their seat in this fast paced and smooth flowing plot. Keri Arthur paints a vivid world with well written scenes and details that capture the imaginatio

Sam has finally snapped over working with Gabriel. His insistence of keeping her out of all police work is too much – she needs to work and be effective. She gets a transfer – to a new case as a bodyguard of a politician. A politician who is really a clone and probably working with either the suspicious military scientists at Hopeworth or the sinister secret organisation of Sethanon… or maybe both

Of course, both Hopeworth and Sethanon are extremely interested in Sam and her unique biology – and

Sam is on cusp of remembering her past. A past she wanted to erase. She is putting her life first and foremost; her first action is severing her partnership with Gabriel. Sam is tired of being cooped up in the closet like office, no more! Her new assignment is with the clone of the Wetherton, which may place her in more danger than she realizes. At this point Sam is far to determined to care…. She wants answers!

The anticipated final book in The Spook Squad Trilogy is brilliant, though I do have to admit that I am gutted that there won’t be any more in this series. The final book answers all questions and of both Sam’s past and future. A wonderful series and a fantastic end to it, I would recommend this series to anyone and everyone to be honest. I loved it.

I love this series so much! Gabriel drove me crazy and Sam continued to be her determined independent self.

Sam and Gabriel were partners until Gabriel's machinations succeeded in making Sam quit. She took a job guarding the clone of Dan Wetherton and trying to find out what he is up to.

Gabriel may have gotten her to quit and that should have meant she would be safer, but then she goes and takes a job doing something even more dangerous. He wants to start a relationship with her now that she do

I've read an reviewed the other books in the series and find Penumbra the weakest of the lot. Turns out there was originally a fourth book planned but a publishing contract for another series got in the way.

To start off, I would not recommend this book to readers new to the series. It picks up right where the last one ended and doesn't give bits here and there to update new readers. This I really liked. I get tired of reading some series which are 10 or more books into it and the author feels co
