Description
We can't tell you who we are. Or where we live. It's too risky, and we've got to be careful. Really careful. So, we don't trust anyone. Because if they find we just won't let them find us. The thing you should know is that everyone is in really big trouble. Yeah. Even you. The pint-sized Helmacrons may have departed Earth, but they haven't finished causing trouble for the Animorphs and Ax. They left behind a damaged ship-containing morph-tracking technology. Now the Yeerks have found the show more ship and are launching a full scale Animorphs hunt! As if avoiding the Yeerks' new tracking system isn't hard enough, Cassie and the others realize they must keep the morphing cube moving if they don't want the Yeerks to find it. But when Cassie tries to hide the Andalites' cube, it accidentally touches a Cape Buffalo! Now there's a mean old buffalo with morphing powers on the loose. And he could give away the secret of the Animorphs if he charges into the wrong. show lessTags

Simple plot but wow, the implications. The characters are acting more like themselves again, there's more what-it's-like-to-be-an-animal insight and some humor, the violence is getting worse when they have to fight. And this book was all one long fight, it seemed. The Yeerks got hold of a device that allowed them to detect morphing energy, so they could pinpoint the Animorphs' location, and also that of the blue box that gave them that ability in the first place. So most of the book is the team fleeing desperately in different animal forms, trying to elude the enemy and confuse them until at the very end they come up with a crazy plan, that might just work, to destroy the detection device. What really got me was the cape buffalo. At one show more point, Cassie hides in a transport truck from the zoo that holds a cape buffalo (why it wasn't sedated to be in the truck, who knows). She morphed the buffalo to calm it, but then the animal unknowingly touched the blue cube, so it gained the ability to morph. This was crazy. Made me wonder why it hadn't happened in some way sooner in the series. What happens to an animal that can change form, but has no idea it's doing so? The buffalo was obviously confused, but it saw Cassie morphing into buffalo form, so formed a temporary bond with her and then started following the Animorphs around and defending them for a while against the enemy's troops. Then it bumped against a human and started morphing into that form. The Animorphs were really freaked out when it started trying to walk upright and mimic simple words. Also terrified what would happen if the enemy got ahold of this morphing buffalo, so they decided they had to destroy it, but Cassie couldn't bear to do so. However when an ant also gained morphing power and started taking Cassie's form, she was horrified and had no qualms squashing it.
Turns out this book bothered a lot of other readers, because all the stuff about the blue box contradicted what was established in earlier books. Which I totally forgot because it's been so long since I read them. So that didn't bother me at all while I was reading.

I had seen a lot of the fandom dunking on this particular instalment so I was braced for it going in, and... I'm not really sure why this one has such a weird rep? Really the only new thing here is that tidbit that sapience/sophonce isn't necessary to use the escafil's morphing- which is admittedly cool, but not any weirder than the rest of the series. This entry is noticeably shorter than every book prior as well.
A short comment for every book of the series until I get a chance to re-read them. All three of my sons and I loved this series and read every single book - I even bought every single book (most, but not all, used; some through school book sales). I'm excited to re-read them to see how the five main characters develop and to watch all the different transformations again.
The best books appeal to *readers* universally - not children versus adults. These may not be quite worthy of the adjective 'best' but they do have that crossover appeal.
