Lenny's friend Juliet never planned to be pregnant and married at nineteen, but since then she has been the perfect wife with the perfect family. Until her husband Matt drops the ultimate bombshell. Lenny is determined to save the day. So when she's asked to test an app that enhances happiness, she puts scepticism aside and persuades Juliet they should give it a go. Could it really be that happiness is only seven steps away? A funny and moving novel of friendship, heartbreak, and the restorative power of melted cheese.
