Unlikely in Love (A Parker Lake Novel #1)
Olivia Sherwood

Wyatt Holloway returned from three tours overseas in the army a broken man. He'd seen and done things that haunt his days and nights. When he discovers Annabelle Cleaver, the beautiful but quirky girl from high school, needs help on her family farm after the passing of her crazy grandma, he finds himself inexplicably drawn to the woman who'd always held his interest.
Ten years later, the unspoken spark that existed as teenagers still remains. The question is, will it produce fireworks or a dying flame?
