Heather Russo is miserable – work is non-stop, and her love life is in tatters. But she’s not the only one struggling. Her mother, Sandy, is finally separating from Heather’s womanising father, while her grandmother, Bonnie, is grieving her third husband by carrying his urn everywhere she goes… even the supermarket. Sick of everyone’s moping, Bonnie plans a surprise girls’ trip: they’re going to hike the Inca Trail to Machu Picchu!

Heather is a reluctant hiker – until she meets charming Owen on the trail and things start to get interesting. Of course, that’s when Bonnie decides to share some long-held secrets that just might send them all over the edge. With every twist in the trail, Heather learns more about her family – and herself. And as her time with Owen becomes precious, she’s forced to reconsider what she really wants.
