Wolf-Speaker by Tamora Pierce
The Immortals, book 2
Daine’s wolf pack from her former home asks her to talk to the humans in their new territory about the destruction of the land, the water, and the hunting grounds in the new valley they have moved to. But it turns out that the situation is much different - much worse - than anyone could have guessed.
Wolf-Speaker is a lovely Tortall book. Although the main characters are (as usual in Pierce’s books) just a touch too good to be true, Daine makes mistakes and grows and learns throughout the story, and interacts wonderfully with the secondary characters. I particularly like Maura, a young noblewoman who is terrified but brave, and Tkaa, one of the immortals that Daine meets and befriends.
