I love her books, so this has been a must-read for me! I love water-based books, and this is no different. Set in a world where people dive underwater to scour for relics of the Old World, Tempe is diving into the Sunken City in search of answers. And in search of her sister. This is an amazing idea, the setting is awesome, and the characters are intriguing. I really want to know more of this world and see where this will lead! Absolutely magical!
