My my my.

Cassie books can be the best in the series, if they're allowed to be. Of all the Animorphs, Cassie is the one most conflicted by the fight against the Yeerks. She is not simply a whiny moralist, as many readers (and Marco) like to suggest. Yes, she can be annoying; yes, sometimes her actions are wrong, even though they are always guided by the best of intentions. But Cassie is the one Animorph who possesses not just human empathy, but interspecies empathy -- that warmth and tenderness t

Brought to you by The Moonlight Library!

Cassie and the Animorphs find out that their Yeerk ally Aftran has been captured and is going to be interrogated by Visser Three in a few days about the Yeerk peace movement. They decide to infiltrate the Yeerk pool and rescue her. Meanwhile, Ax falls ill with a deadly Andalite infection called yamphut, and it infects the other Animorphs as well. Cassie is left to infiltrate the Yeerk pool and rescue Aftran all by herself, and by the way also needs to perf

A sequel to #19: The Departure, The Sickness moves forward the Yeerk peace movement subplot. And I don’t know how you can possibly hate on Cassie after reading this book, because she literally saves the day single-handedly. She is boss mode.

I mean, if Cassie had been any more successful, she would be a Mary Sue. Not only does she infiltrate the Yeerk Pool, without any backup, by hosting a sympathetic Yeerk, rescue Aftran, evade capture, and make it out alive … then she proceeds to perform brain

Ghostwriter: Melinda Metz.

Oh goshhhh what a great string of books -- I ploughed through several of them in a day, so I'll hopefully keep them straight. This one picks up after #19 The Departure, continuing Aftran's storyline and expanding the world with the revelation that, thanks to Cassie's earlier actions, there's now an expanding Yeerk peace movement within the ranks of the empire. As often happens, a two-fold problem emerges: Ax is incapacitated by a mysterious sickness that is going to lea

"Great character dynamics and action"

This book represented Cassie's personality very well.

I'm used to Rachel musing about her violent nature; Cassie wondering how peaceful she really is was an interesting analogue to that.

Cassie's sympathy for Yeerk sensory deprivation added something to the usual intro. Ax relishing the sensation of human morph was an interesting analogy that I'm glad Cassie brought up. I figured it was foreshadowing of Yeerks morphing.

The dance was comic relief. The main relat

This volume was different than usual for this series, but it was still exciting and fun. Can't wait to read the next one!

I'll admit it - I didn't read all of the Animorphs books as a kid.

I bought a few at thrift stores, random ones - I know I had a few of the Megamorphs books - and I checked the first three or four books out from the library. After that, I just picked the Marco ones out of the long list of books, because Marco was the bomb, man. So, reading this? It was kind of a first-time read. And... uh, I didn't know a lot of what had happened, because even though there are recaps, (view spoiler)

Ax comes down with a terrible sickness, and since unlike humans he can't throw up, he ends up with a fatal swelling of one of his glands. While they wait for Ax to get to a certain body temperature so they can do brain surgery on him and save his life, they also get word that Aftran, the Yeerk Cassie formed an alliance with, has been found to be the founder of a Yeerk peace movement. Delivering this news is Illim, a Yeerk who lives in one of their teachers, and he is also part of the peace movem ...more

Aftran is captured by Visser Three and risks spilling the Animorphs identity after spending time in Cassie's head a few books back. To make matters worse, Ax contracts a sickness and requires medical attention. The other Animorphs succumb to illness, resulting in a solo effort by Cassie to save Aftran AND to save Ax. This book exposes the Animorphs to the Yeerk Peace movement. I liked how this book connects to a previous one and emphasises how Cassie and the group are not alone in fighting again ...more

An intense choice, to push Cassie out all on her own. I like seeing the group start to fracture a bit simply because it's realistic. There can't always be a unified front, so when Ax falls to an illness and takes most of the group with him I believe the stress and uncertainty Cassie has. Her ingenuity shines here and I love love love the way the group solved the problem with Aftran. Brilliantly done, guys.

I also really liked that Erek is becoming a bit of a series regular and that more Controlle

So badass. If I'm a guy or lesbian or any gender who likes girls, Cassie's definitely going to be my type of girl. Haha. You think she's so weak but do something stupid and Cassie'll be there to - gods I don't even have the heart to tell you. XD

In this book all the animorphs got sick! Even my dear Ax was sick, in fact Ax almost died :O I was in the bus while re-reading this and I didn't care at all if my seatmate gives a fuck that I look terribly sad earlier. My favorite Alien's going t

I really like this once. Nice pacing. Nice action. Intense decisions that had to be made and stunning resolutions. Not only that it was pretty well written and while there were some plot points you had to whistle past, they were well worth the whistling. I love how complex a character Cassie is and how much compassion she has despite what she's up against. I really like too the direction the series as a whole is turning in.

Though Visser Three is still a mustache twirling idiot of a villain. Can

I absolutely loved this one! Altran the Yeerk (although I keep calling her Karen in my head) reappears! I still think the book where she first appears is the best in the series, so I was thrilled to find out what happened to her.

I think that (view spoiler)

I also loved the dance scene at the beginning, mostly because I love seeing Rachel and Tobias together
The irony of reading “The Sickness” this time around – I was actually staying home sick, though thankfully not as sick as the Animorphs got. In this book, the intermingled story lines worked well together: save Aftran the Yeerk from Visser Three’s interrogation and certain death, and save Ax from the Tria gland in his head exploding. Can you see where this is going?

Cassie is the only one who doesn’t end up falling sick (naturally – she is narrating, after all), and so she must visit the Yeer

Everybody but Cassie gets sick, leaving her alone to fight on an important mission, only to come home to perform brain surgery on Ax because Andalites don't puke. Bird poop saves the day!

Notable moments and inconsistencies:

This book is ghostwritten by Melinda Metz.

It's clear that the Yeerk Aftran has managed to start a peace movement somehow, but it's not clear how she was answering for not being in her host, who was supposed to be a young girl named Karen planted to watch the girl's dad and rep

The Sickness is one of my favorite Cassie books, in part because there is very little of her moralizing. But beyond that, it's one of the most exciting in the series. Everything is go, go, go, as the rest of the Animorphs are put out of commission by an Andalite sickness. Cassie has to infiltrate the Yeerk pool, rescue Aftran, and escape in time to perform brain surgery on Ax. This is the best heist in the series, and one of the few books where one Animorph truly does it all. Way to go, Cassie!

We're getting into the segment of the series that I haven't read before, so I didn't know what to expect - I think this or #30 is the last one I have any memory of. I was expecting worse from ghostwriters, since that's what I heard from people. But I have been pleasantly surprised. This is a wonderful Cassie book, and a great book overall for the series.

Cassie, kind-hearted tree hugging Cassie, was the hero narrator for the novel. Ax catches an alien sickness which happens to be contagious, crippling out almost all the animorphs. Unlike Ax, whose life was threatened by the disease, the humans only suffered the same ordeal influenza would have handed them.
The only animorph left in it shape to fight was Cassie, who was now handed the mission to save a yeerk that was captured by visser one and save Ax from dying.
Not easy, seeing as she was to infi
This is probably one of the most depressing Animorphs books in the whole series. I actually read this as quickly as I could because it was putting me in a bad mood. Basically, Ax is sick and all the other Animorphs get the flu except Cassie. On top of that, the "mission of the week" (or whatever you want to call it) is to save that Yeerk named Afran (sp?) because she's going to be questioned by Visser Three. Not only does Cassie have to morph into a Yeerk to get inside the Yeerk pool and save Af ...more

All power to Cassie in this one! An interesting morph choice and a great ending opportunity. Finally taking advantage of their resources really well. Also nice to realistically have someone be dangerously sick.

One thing about this book sticks out in my mind, some ten years after finishing the series: "Bless your baby bones." Random , right? But I guess it's because I was really touched by the tenderness Cassie shows to Ax in that scene. I always felt bad for Ax, stranded as he was on an alien planet, part of the Animorph group but somehow separate. He always seemed like such a lonely character. But when he was sick it was like he became more vulnerable, whereas before he was usually very formal and st ...more

It was interesting watching Cassie try to handle this on her own. She did a pretty good job of it though I do think she takes some naive risks sometimes.

Fantastic SiFi series for a young reader. I enjoyed reading these with my daughter. The storyline is good and the plot interesting, wouldn't take much to make these great adult SiFi stories. Highly recommended

Cassie's not my favourite but when she comes through, she comes through. Sometimes she can be really strong and I really admire her.
This was a very nice book which has made a different Cassie than the first tree-hugger.

The Sickness was intense. Ax gets really sick. They have to help Ax while rescuing a Yeerk of the Peace Movement. Visser 3 captures Aftran942 (kind of). Afrtran is already a Yeerk (of the Peace Movement) and Cassie and the other Animorphs, minus Ax. And then the others get sick, except for Cassie who must act alone to complete the mission of saving Aftran942. And then Aftran is rescued will die of kandrona starvation.
