The Gift From Within — Alice Gaines

Rick Harrison has a lot to forget. After the war, he's holed up in a tiny cabin in Maine where he'll never have to endure heat again. He's cut himself off from all of humanity as he doesn't feel very human himself. When a woman named Leeza shows up on his doorstep in the middle of a blizzard, he takes her in to save her life. Little does he know that she's going to save his life, instead.
