Never Let You Go by Erin Healy. Erin is the co-author with Ted Dekker of two novels: Kiss and Burn.
In Never Let You Go, Lexi is a single mom who is struggling to make ends meet, and still make time for her daughter. The story opens when people and events from Lexi's past literally come back to haunt her. It's a supernatural thriller, but still a believable story about very real characters. I especially appreciated how Lexi came to understand how God was working her life in ways she couldn't at first understand, to restore relationships and heal her family. Intriguing read!
