Do you love Marian Keyes, Sophie Kinsella and Jill Mansell? If so, Stella Newman is for you!

Is there a formula for happiness?

If it's Netflix, two-for-one Malbec and the perfect toasted-cheese sandwich, Lenny has it covered. But when her friend Juliet finds herself at rock bottom, Lenny realises it's going to take more than that to fix her.

Luckily help is at hand in the form of HappyGuru: a plan which promises happiness in seven easy steps. So when Lenny is asked to research it, she puts scepticism aside and persuades Juliet they should give it a go.

The friends quickly find themselves immersed in mindfulness, juice cleanses and death-defying circus stunts. Yet as Juliet becomes increasingly buoyant, things only get more complicated for Lenny.

Can it be that happiness is only seven steps away?

A funny and moving novel of friendship, heartbreak, and the restorative power of melted cheese.
