Aidan Brook has spent months living with the horror of what happened when she lost control of her magic. Now she's searching for a way to manage her immense power, but she only hits one dead end after another. On the run from a council intent on her death, Aidan, the bear shifter Mac, and the rest of her friends find themselves on a desperate chase across deserts and oceans in search of answers. Along the way, they encounter a living myth and a dual magic with secrets of his own-and they learn that the cure may be more deadly than the disease. To save her own life, Aidan will need to confront the most dangerous foe she's ever faced...herself. LOST CAUSES is the fourth book in the award-winning Elements urban fantasy series.
