Taking place roughly 7 years after the conclusion of the Alanna quartet, Immortals focuses on Diane, a thirteen year old girl who has Wild Magic (a nature based power distinct from the Gift, a human based magic). Pierce weaves Diane's story through many of the old favorite characters, which was appreciated.

This books feels more "kid"-like than either the Alanna series or Protector of the Small (which I put on pause to go back and complete the Immortals series). This may change as the characters get older and more mature (like Pierce did with Alanna). Also, Daine doesn't seem to struggle with much, which is very unlike Alanna's character evolution. She is very strong in her magic, and it seems like things fall into her lap without much work or sacrifice on her part. I'm hoping this changes as the series progresses.
