Six years ago, Ivy Marlowe's engagement to billionaire Nathaniel Calloway ended without warning, days before their wedding. Now a rising interior designer, Ivy walks into a pitch meeting only to discover the client is Nathaniel himself — and that he's spent four years quietly running a nonprofit design firm bearing both their names. Just as old wounds start to reopen, a family emergency forces a secret to the surface: their breakup was never what either of them believed. As Ivy's mother reveals the truth about a hidden "wedding fund" and the real reason the engagement was called off Ivy and Nathaniel must decide whether six lost years can be forgiven and whether the second chance neither of them asked for is one they're brave enough to take.
