What is this I can’t even.

#21: The Threat strips away any remaining pretensions that this is a “children’s” series. This is YA at its grittiest. Long before we had people volunteering themselves as tribute and running through mazes and choosing which Personality House they belong to, we had David the Traitor betraying the Animorphs because he is a terrible human being.

We’ve seen this theme before in the book. Applegate reminds us that humans have the capacity for great acts of courage (see: the

The structure and pacing of the David trilogy is so unbelievably good. I think this review will vaguely spoil the gist of this arc in general (but then again, so do the taglines on the covers, so...), but not in specific. Taking a moment to look at how KAA constructed this:

The Discovery: It's so fitting that this one is narrated by Marco, the guy who gets along least with David -- because it also makes sense, because Marco has an abrasive personality that is likely to rub many people the wrong w

Brought to you by The Moonlight Library!

Things with the newest Animorph, David, aren’t going so well. He’s reckless, unmoral, and a coward. He’s also the biggest threat to the Animorphs since they started their war. He knows their secret, and he has their power…

I absolutely love the David trilogy. David is unlikeable from the first time we meet him in The Discovery. Even though this novel is short, his character growth is phenomenal. He grows from a little reckless, quite frightened by morphing,

Second in the "David" trilogy. David proves to be one twisted little sicko. Even though the Animorphs are good guys, they may have to think like bad guys in order to stop David, because after all, they not only have themselves to think about; they are the only force stopping the Yeerks from taking over for good. They can't let this little snot wreck their group. But what can they do without becoming evil themselves?

Notable moments and inconsistencies:

I can't believe that one kid from Toy Story is an Animorph


I know he's awful and all, but I kind of love David. I mean, come on, he has a snake called Spawn and a cat called Megadeth. He can't be that bad. Also, I may have a bit of a weakness for massive edgelords... :x
     Book two of the ‘David trilogy’ in Animorphs, and things are getting heated. Not only are the Yeerks plotting a huge event to get to make Controllers of many heads of state, but there is also trouble with the shaken-up balance of the Animorphs with the addition of David to their numbers. David’s now been active in a couple missions, and Jake and the others are getting a better feel for David’s character and how he reacts to events. Some of David’s “jokes” and opinions seem to be cause for c ...more

Wow. What I really appreciate about the David storyline is how it forces the kids to consider exactly what morally ambiguous things they need to do to keep themselves and the world safe. Up until now, they've been fairly virtuous, but they're running out of choices. Friendship isn't enough anymore; morphing power isn't enough, either. In fact, both of these can be corrupted and used for evil. It's chilling.

It's interesting to compare the messages in this one to those of the Cassie narration a co

This book was gripping at its end. it is part 2 of a three book story arc (book 20,21,22). I cannot imagine 8-12 years olds being the target audience for these books reading this. This is some seriously mature dark content dealing with incredibly intense issues of morality. This book was riveting!!!

This one is really intense and actually made me tear up at one part. It also ends on the WORST cliffhanger and I can’t wait to read the final part of the trilogy!

After a narrow escape from their investigative mission on the Yeerk Blade ship, the Animorphs hatch a plan to infiltrate and save the world leaders from being infested by Yeerks. They're also still getting used to their new member, David, and have some disturbing conversations and revelations about him. He seems insubordinate, confused, and possibly dangerous. When they sneak in to scope out the place where the world leaders' banquet is going to occur, they uncover some tricky Yeerk holograms an ...more

Now David is saying and doing some really nasty things instead of just being obnoxious.

The mission *is* more important than Saddler. And I don't see what Jake could do for the boy, so any involvement by him would seem like an empty gesture anyway.

It's good to hear about Marco's dad dating again, though that fact crimps these particular plans.

Having trouble sneaking in within the two hour morph limit was nice as a different sort of close call. I was reminded of a moment earlier in the series wher

The Threat is probably a little stronger than the previous instalment but still comes across as being largely filler. It is very much the middle book of the trilogy - ramping up the tension in preparation for the final act. While the first two thirds of the story are taken up by the B-plot concerning the world leaders (resulting in an incredibly silly attempt made by Visser Three to trap the Andalite Bandits), this ultimately does not really go anywhere and just serves as a vessel for David's in ...more

The 21st book in the series by Applegate and the second science fiction book I picked up after an astounding experience with ‘The Threat’, second in the Animorphs series. Science fiction has dangerously crept into my interest. Morphing back into the teenager, I was hooked to ‘The Threat’ and couldn’t wait to lay my hands on this one and it would be an understatement if I were to mention I liked the book. Though I missed about 18 books in the series my hiatus was compensated by a brief introducti ...more

It's been kind of a dry spell for me so I was a little confused diving right in-- but man this book is pretty tense! It really kept me on the edge of my seat-- wondering how they were going to get out of the situation they were in. The last chapter or so was especially good when it came to drama and tension.

The David Trilogy continues! As this is part 2, it starts right in the middle of the action that book 20 left off on...the Animorphs in cockroach morph falling from a plane. This adventure is told from Jake's perspective and I thoroughly enjoyed his insight. There's a lot he's got to think about; saving the UN from becoming evil alien Controllers and of course what to do with the newest member of the gang, David. And David isn't really fitting in. He's impulsive and as Rachel points out, a cowar ...more

The 21th story about Animorphs. Jake the Leader.

As teenager, Jake must face and handle a lot of trouble. Well, he's the leader of our small battle team names Animorphs. He must take a decision about dead or alive on long battle against Yeerk.

This time, he must deal with a huge mission and a new member of Animorphs, David. First David looks like a great addition to the team, he knows something that the others don't know, he battle well. But, David is an a**h*l3. He trying to betray the others, tr

Like #17, I have to complain about the cover. Why don't they show Jake morphing into the dragonfly? That would have been so badass! Anyway, this is an excellent book, and the most memorable that make up the David trilogy. The Animorphs are on a mission to stop Visser Three's plans, but wait! It's a trap. And on top of that, David is a traitor. This book is a more interesting read, with quite a few twists. The way the characters interact with David is awesome. He basically reminds you of that dis ...more

Ok, I really hate this guy. There is obviously something a little more than broken in his head. It drives me nuts that Jake doesn't recognize all the signs. I think Jake grows the most so far as a leader in this book. This is the first book where he actually acts like a leader instead of just being so in name only. The animorphs become more militant.

Jake is also faced with morally complicated situations that there is really no right answer to. Abandon David, kill him, or let him join. Having a g

Just as Marco was the perfect narrator for our introduction to David, it's appropriate that we see David's betrayal through the eyes of the Animorphs' leader. Jake struggles with the unknown factor that David introduces to the tight-knit group, and with David's abuses of the power to morph that the rest of the group has avoided implicitly (one effect David has is making you appreciate the original group and their dynamics even more). The series has dealt with some heavy subject matter already, b ...more

Seriously though, this whole David storyline is both gripping and agonizing. This is part two of three and I jumped straight into part three when I finished so I'm going to just move along. But I have distinct memories of the showdown in this one, between Jake and David, and rereading it wasn't any less agonizing this time. And this might be the best Jake book in the series so far-- it definitely feels the strongest, where Jake is finally maybe coming into his own and realizing and weighing to c ...more

This single book has revived my interest in the Animorphs which had started to waver after 20 previous books. I never got this far reading the series as a child but am glad to be reading through it now as an adult. I do really think that so much more could have been done with the series but it feels from this book that the stakes have been raised and the real threat is starting to loom. Characters we loved may not all make it.

I knew I wasn't wrong when I decided to continue the Animorphs series from where I left off in my childhood. This book totally gripped me and I never thought of putting it down. I wanted to find out what kind of creep David is and I sure did. I hope the Animorphs take down that miserable, filthy excuse for a human being.

OTRA VEZ UN FINAL CON CONTINUARA? Ya empiezo el que sigue, pero antes varias cosas:
1) David es un *****, en el libro anterior me cayó muy mal y en ese ya lo odio, no lo quiero ni ver.
2) Tobias se llega a morir y voy a estar llorando por una semana.
3) Necesito saber que es lo que esconde David, yo se que algo esconde pero no lo dicen!

I feel like the shorter format of these books actually hurt the story a bit even if it was part of a larger story arc. Some of the feelings and ideas would have been better with more development, but it was still a tense and exciting read.
