For Love's Sake by Cynthia Rutledge

Caretaker Rachel Tanner thought her life was perfect until she took on the assignment of bringing hometown hero Jay Nordstrom back into the land of the living. She'd loved him from afar and hated to see him so broken. Nevertheless, Jay's charismatic personality shone through, and soon Rachel was in danger of losing her heart once again.
A devastating accident had almost destroyed Jay's will to live. No bit of sunshine could tempt him to believe in goodness, but then Rachel swept into his world and opened the curtains. She showed him how much he'd missed by abandoning God, how faith would empower him. Jay searched his soul to express his gratitude...and growing love for her.
