SO GOOD! This book has plot twists, action, adventure, friendship plus romance, so basically, what you would want in a book. Read the whole series! The only book better in the series is Nightfall (book 6). Also, Sophie+Keefe for life!!!!!!!!
AWESOME!!!!! Ms. Messenger went above and beyond my expectations for this book(I said it had to be better than book 5). Can't wait for book 7 in fall 2018! If you love this series you'll love:
The Land of Stories
Wings of Fire
Percy Jackson and the Olympians
The Heroes of Olympus
The Kane Chronicles
The Isle of the Lost Treasuries
This book was AMAZING! This book was just as good as Percy Jackson and I think I may even like Heroes of Olympus better. My only disappointment was that I didn't like Jason as a character at all, but Piper was a great character and Leo was AWESOME and hilarious! This is an expansion on Percy Jackson so if you liked Percy Jackson you will LOVE this series.
