The world building is exquisite as always, and the personalities of dozens and dozens of animals are all well drawn. Thorn's angst gets to be a bit repetitive, but he really wants to do what is best for his tribe and for Bravelands; that's a big responsibility, so it deserves adequate exploration. Sky also has a lot on her plate, and it's interesting to see that the cubs' aunt wouldn't take care of them, but Sky was very accepting of falling into the caretaker role.
Readers who like books about animals who have well established tribes and territorial wars frequently only want to read similar books, and Bravelands is an interesting series because it involves a variety of animals, making it a little easier to tell the characters apart (unlike Warriors, where all the characters are cats with similar names!). I can't think of too many books set on the African plains, making Bravelands an intriguing choice for children who couldn't get enough of The Lion King and want to transfer their love of that film to literature.
