When You Forget Me - Lorelei Johnson

Elspeth is cursed: everyone she meets forgets her the moment they look away. For two long years, she drifts through life like a ghost, desperately seeking someone powerful enough to break her lonely, vanishing spell. Then she meets Roman—a formidable vampire enforcer whose instincts whisper that she is his destined mate. But witches don’t have mates… and if he falls for her, will her curse destroy them both? As her past closes in, only time and memory will tell whether love—or oblivion—prevails.
