In Love with a Rebel by Ginny Sterling

A new beginning was the ultimate nightmare for this proud, wounded soldier.
Max Collins had always wanted to leave Afghanistan – just not on a stretcher. A severe injury, a frightened hope, and life-threatening mistake sent him careening on a one-way trip to the opposite side of the world, facing a ghost from his past. Now, in the middle of nowhere, attempting to pick back up the pieces of his life, Max is knocked down once more… by the most frustrating woman, Daphne.
