Leading up to Crystal Crowned, the last book in the series, you need to read Waters Wrath. Reading Waters Wrath will change your view on a select few characters but you will appreciate it so much.
Elise wrote the book so well and it just pulls you in. It pulls you in so far you feel like you are actually part of the story.
I know you think "What does she mean?" Well I mean that the characters feel like a family you have never had. That's how I feel.
Vhalla is still so amazing and so is Aldrick and every other character in this book.
I recommend this book because it is so amazing and heartfelt.
