Katherine Heiny, author of the hugely beloved Standard Deviation, returns with an eccentric, warm and hilarious new novel.Jane easily falls in love with Duncan: he's charming, good-natured, and handsome. He has also slept with nearly every woman in Boyne City, Michigan.Jane sees Duncan's old girlfriends everywhere – at restaurants, at the grocery store, even three towns away. While she may be able to come to terms with dating the world's most prolific seducer of women, she wishes she didn't have to share him quite so widely. His ex-wife, Aggie, still has Duncan mow her lawn. And his coworker Jimmy comes and goes from Duncan's apartment at the most inopportune times. Jane wonders how the relationship is supposed to work with all these people in it. But when tragedy unexpectedly tears through that shared life and relationship, Jane’s life will become permanently entwined not just with Duncan (no matter what, she can never have Duncan to herself) but Aggie and Jimmy and seemingly all of Boyne City. But maybe she can find a happiness in that; a happiness all of her own.A novel that is alternately bittersweet and laugh-out-loud funny, Early Morning Riser is Katherine Heiny's most astonishingly wonderful work to date.
