Lost in Love by Vivian Porter

Ethan Yates and Zoey Reid know a thing or two about loss and loneliness.
After losing his parents in a car accident, ex-Marine Ethan moves to Hot Springs, Arkansas to start his life over, never expecting to find love in the unlikeliest of places–Lake Bennett National Park.
Zoey, a recruitment officer for the park, is used to being on her own, and she won’t risk her heart–or her independence–for just anyone.
But when her job is put on the line, she must choose between fighting the battle on her own… or learning to trust the man who longs to stand by her side.
There you go.
