Oh, you thought this battle was already epic? How about when the Animorphs get pulled in as the players in a grand-scale gambling game, fighting for a nigh-omnipotent creature named the Ellimist?
26 was awesome. The Animorphs (fighting for the Ellimist) have to fight the Howlers (who are on Crayak's side). In a completely unfamiliar environment. Without understanding of their motivation. Gosh, like they don't already have enough to worry about.
Notable moments and inconsistencies:
This book opens with a prologue--not the usual fare for Animorphs--and makes reference to the events of a previous book, when Jake was infested with a Yeerk. He remembers that after the Yeerk died, he saw a vision of a creature with a red eye that could see him. Way back when that happened, readers had no context to understand who/what was looking at him, but in this book we finally get to find out what that was all about.
The Iskoort race is introduced in this book. They communicate through thought-speak like the Andalites, but have a honking/wheezing ability for vocalizing, which comes from their stomachs. They are very pushy, like alien salespeople, wanting to sell or receive services without a care for whether the targeted party is interested.
Not that it's impossible, of course, but it's odd that of all the people to lose balance and be knocked off a platform, it'd be Rachel, who's a gymnast and has experience balancing on various gymnastic equipment.
The Howlers are introduced part-way through the book; though they've been mentioned before as the executioners of the Pemalite race, they've never been described until this book. The narration describes them as being on the large side of man-sized, formed out of a black lava-looking substance with red cracks, having blue eyes, and having a rotating mid-section and human-like hands with a set of wrist claws above them. They regenerate limbs and have a powerful howl that can paralyze victims. They also carry a lot of weapons, and--unbeknownst to most--have an extremely carefree, happy disposition, not entirely unlike the Pemalites. Making war is a game to them, and they're all children.
Cassie is unusually cynical and pessimistic in this book, though she's still very caring and empathetic. Jake's narration comments on how unusual this is several times.
This is also the book in which Jake and Cassie have their first kiss. Rachel's response is, "It's about time."
A thought-speak tag failed to close during a conversation shortly after Jake morphed a Howler.
The other races that the Howlers had destroyed up to that point besides the Pemalites were called Graffen's Children, Mashtimee, Pon, and Nostnavay. They will also be attacking the Sharf Den in the future.
