When their worlds collide that summer, the three teenagers form a bond they believe will be unbreakable. But life doesn't always go to plan...Now. Shocking news brings Leah back to Yorkshire, baby daughter in tow. But Emilie's father Theo isn't with them, and George has unexpectedly returned. After half a lifetime, have they healed the scars of their pasts? Will coming back home set their hearts in a different direction?
