Slade by Serena Simpson

Mila spent her life hiding away in and out of hospitals. Only one sister could have a life, and she wasn’t the one that was chosen. Her best friend, her replacement sister invited—ordered her—to move in with her and her family.
It would have been perfect if tall dominant and oh so sexy Slade wasn’t watching her with green eyes sent from the Gods, and a mouth made for sin. Time always felt like it was standing still, now it was rushing to catch her. The enemy that tried to kill her as a preteen was back; now it wanted her and the sister who didn’t know she was still alive.
Could she sacrifice herself again so her sister could live? Or did she finally want a chance at life with the one man who made her feel life was precious?
Slade was a rage-filled male with nothing to look forward to. When they told him that another human female was coming to live with them, he shrugged. What was one more? Then he met her.
Her scent teased her with thoughts of a future that couldn’t be his; Mila was so much more. How could he even want to talk to her when another held his heart for so long? Slade needed to learn how to let go of the past and embrace the future before Mila was forever beyond his reach.
Together they must defeat the horrors of the past if they ever want a future together.
