SPOILER ALERT!! In this book Cara is in the land of the unicorns and gets captured by the delvers. She makes a friend in their jail and names him Rocky. When a delver gets thrown in a delver jail they do not get to keep their name.:( They escape from the jail safely without getting hurt but a lot of their other friends got hurt from helping Cara and Rocky. In the middle of the book she finds out that Beloved their sworn enemy is trying to make a portal to Luster to kill all the unicorns. In the end of the book Beloved gathers her helpers known as the hunters and opens the portal to Luster on the night of the blood moon and then the book is over. I loved this book because, it had a lot of detail and adventure along the way. I also liked it because, it has a lot of fictional creatures such as the Dimblethum, Unicorns, Trolls, and a Squijium! This book was a very great mystery/adventure bok. I loved how everyone wanted to help each and other to fight their sworn enemies. The Hunters.
