The Animorphs books begin with a tale of Evil Yeerks invading Earth and the Andalites the distant heroes who can come save everyone if our young heroes last long enough for them to arrive.
And it keeps that facade intact for our young heroes for, oh, about five and a half books.
Then Jake, after boiling a hundred Yeerks in a Jacuzzi without a second thought, watches Temrash 114 die slowly and painfully while controlling his own body. Even knowing Temrash will doom Earth if he escapes, even knowing that Temrash has broken his own brother into a shadow of himself, Jake feels real sorrow.
Then Ax calls his people for help and is given the blame for his brother's crimes because the Andalites can't tarnish a hero's reputation in the middle of their long-running war.
Now here's Eslin Three-Five-Nine. Not an "ally" by any stretch, but he hates Visser Three more than he hates the Andalites. Because Visser Three lied to him. Because he lost Derane Three-Four-Four.
It's just the beginning. Just the cracks.
