MEET ELLIE. She's perfectly happy living a quiet life with her husband, Clive. (Well, she does sometimes wonder about the way he talks to her, and about all the things she hasn't achieved yet. But, she's happy enough.)
MEET DAN. He's definitely content - content with his predictable, ordered existence, making harps in his isolated barn on Exmoor. Content being on his own, far away from other people and - crucially - far away from any risk of surprises.
What Ellie and Dan don't know yet, is that a chance encounter is about to change all of this . . .
