Shadow Seer by Jennie Lynn Roberts

Their Shadows recognize each other immediately. Their hearts need a little more time…

Emma wants nothing to do with the Order. She fled that life—and accepted that she would never be a Seer—years ago. But when her childhood best friend arrives at her door, everything changes.
Zach’s on a mission. It’s up to him to stop the blood Shadows and Emma might be his only hope. Trusting her, though, that’s complicated… and Zach’s been betrayed once already. What is clear is that Zach’s Shadows have claimed Emma’s and losing her is not an option.
Time is running out and their enemy has the upper hand. Zach and Emma will need to trust each other if they want to overcome the danger ahead. Will they take a chance on love, or walk away and face the darkness alone?
