Big Swiss 'Incredible book. . . I couldn't put it down.' Jodie Comer

Greta liked knowing people's secrets. That wasn't a problem. Until she met Big Swiss. Big Swiss. That's Greta's nickname for her - she is tall, and she is from Switzerland.

Well that's how Greta imagines her; they haven't actually met in person. Nor has Greta actually ever been to Switzerland. What Greta doesn't know is that she's about to bump into Big Swiss in the local dog park.

A new - and not entirely honest - relationship is going to be born. A relationship that will transform both of their lives.
