Lost Down Deep by Sara Davison

She is the only one who can tell the police who attacked her in her home.
If only she could remember …
Summer Velasquez is on the run from a man she has no recollection of after an attack she can’t recall.
Every face in the crowd is a potential suspect, so how is Summer supposed to know who is a threat to her and who isn’t?
After fleeing her assailant and the parents who lied to her about what happened, she changes her name and seeks refuge in Elora, Ontario. The small town feels familiar, although she has no memory of ever having been here.
Even in what should be a safe place, she can’t shake the feeling that she is being watched.
When Ryan Taylor strolls into the Taste of Heaven Café where she works, Summer is immediately drawn to him. However, he may not be who he says he is either. As her suspicions grow, Summer prepares to run again.
But at least one person is determined to stop her. Permanently. And if she can’t remember who he is, this time he may succeed.
