Early Morning Riser by Katherine Heiny

Duncan is charming, handsome – and Jane falls in love with him easily.

But he has also slept with nearly every woman in Boyne City. Jane sees Duncan’s old girlfriends everywhere – at restaurants, at the grocery store and his ex-wife, Aggie, still has him mow her lawn. But everything changes with one tragic accident.

Now her life is permanently intertwined with them all and she knows she will never have Duncan to herself. But is it possible that a deeper kind of happiness is right in front of her eyes?
