Eyes in the Storm by Jeff Smith. This series gets better and better for. The first book introduces the main characters, the second book develops the story arc; and the third one starts it all rolling.
Bone and his friends have somewhat recovered from the Great Cow Race but things are about to get interesting. Thorn starts having strange dreams and begins to search for answers about them, Bone’s cousins have to face the music with some trouble they started in Book 2, and Bone’s crush on Thorn gets progressively worse.
I like that Grandma is such a strong character despite being old and a woman. I like it that humor is thrown in when I least expect it. I like the mystery and angst. I like that Bone loves his Moby Dick. And the rat creature creep me out.
