From the Sunday Times bestselling author, for anyone who's ever been ghosted - and wondered why...
'Unputdownable' Mel Giedroyc
'Beth is a really clever, funny writer' Nina Stibbe
'The queen of feel-good fiction' Clare Pooley
'Isabella's NOT dead.'
Every time someone asks Gwen about her best friend - you know, the one who ghosted them all fifteen years ago - this is what Gwen tells them.
But where is Isabella? Why did she leave, just when Gwen needed her the most?
Setting out to solve the mystery, in an adventure that takes Gwen across the country then across Europe; that tests her friendships and strains her marriage, Gwen searches for Isabella.
But Isabella's not the only one who's lost. Is Gwen also searching for... herself?
