Walking on sunshine

After Mike loses Pia, his partner of seventeen years, their best friends Vicky and Zaza try to help pick up the pieces.

But though Pia's gone, she left a plan. A list of loving instructions to help Mike and her friends come to terms with their loss.

And they're each going to need it . . .

Just-engaged Zaza fears committing any further.
Exhausted mother and wife Vicky has lost sight of herself.
While Mike just feels all the colour has gone from his life.

When the list sends them trekking to Peru, where high mountains and sweltering rainforests push them to the brink, all they have to guide them is their faith in Pia and in themselves.

But will they learn that anything is possible when you're walking on sunshine?
