Wicked Magic by Luna Pierce

A powerful witch, four devoted men, and a curse so wicked it could ruin them all.

With two curses broken and another one knocking at her dorm room door, Willow Oliver can’t seem to catch a break. Is the constant string of unfortunate events just a normal case of bad luck or something else?
A week is all she needs to give the Reperio Stone enough time to recharge so she can locate her mother, but her plan is railroaded when everything takes a turn for the worst.
With a man she loves being held by the darkness, and the unknown whereabouts of her mom, Willow has a choice to make—one that could change things forever.
The best and worst are yet to come.
