Cipher (Southern Arcana #4)

Fourteen months ago, Kat Gabriel's life changed forever when she used her empathy as a weapon. Now she can't escape the weight of those deaths--or the loss of the easy friendship she and Andrew once shared. Obsessed with her mother's violent past, Kat is determined to learn the truth of her inner-darkness by understanding her legacy.

Since the attack that turned him into a wolf, Andrew Callaghan has done everything possible to make himself stronger. More capable of protecting Kat--both from the supernatural world that forced her to kill, and from their own volatile connection. Pushing her away hurt them both, but he's finally made himself into the protector she needs.

As Kat's quest leads her into the darkest underbelly of the psychic world, Andrew is determined to be at her side. But every step forward reopens old emotional wounds and shakes their control. For a dangerous alpha and a deadly psychic, distraction could be fatal--especially when the greatest threat they pose is to each other.
