In the darkness we all need a little light . . . After Mike loses Pia, his partner of seventeen years, her best friends Vicky and Zaza try to help pick up the pieces. But though Pia's gone, she left a plan. A list of love and instructions to hold Mike and her best friends together. And they're each going to need it. Just-engaged Zaza fears committing any further. Mum Vicky can't see a way past her kids and back to her career. While Mike just feels lost without the love of his life. But when the list sends them to Peru, where high mountains and sweltering rain forest take them to the brink, all they have to guide them is their faith in Pia's instructions and themselves. Did anyone say Walking On Sunshine was easy?
