It Ends with Us by Colleen Hoover

Lily hasn’t always had it easy, but that’s never stopped her from working hard for the life she wants. She’s come a long way from the small town in Maine where she grew up — she graduated from college, moved to Boston, and started her own business. So when she feels a spark with a gorgeous neurosurgeon named Ryle Kincaid, everything in Lily’s life suddenly seems almost too good to be true.
