Rose Mortiz has always been a fixer, but lately she's been feeling lost. She has brand new powers that she doesn't understand, and her family is still trying to figure out how to function in the wake of her amnesiac father's return home. Then, on the night of her Death Day party, Rose discovers her father's memory loss has been a lie.

As she rushes to his side, the two are ambushed and pulled through a portal to the land of Adas, the fairy realm. There Rose is forced to work with a group of other powerful teens to save Adas. Soon, she begins to discover the scope of her powers, the troubling truth about her father's past, and the sacrifices he made to save her sisters. But if Rose wants to return home so that she can repair her broken family, she must figure out how to heal Adas first.
