I Found You - Lisa Jewell

'How long have you been sitting out here?'
'I got here yesterday.'
'Where did you come from?'
'I have no idea.'

Surrey: Lily Monrose has only been married for three weeks. When her new husband fails to come home from work one night she is left stranded in a new country where she knows no one.

East Yorkshire: Alice Lake finds a man on the beach outside her house. He has no name, no jacket, no idea what he is doing there. Against her better judgement she invites him in to her home.

But who is he, and how can she trust a man who has lost his memory?
