A Wigwam for a Goose's Bridle

After Susie dies suddenly, her sister Camilla receives a set of letters, sending her on a quest from Australia to London and a small French island. Susie had travelled after school and returned heartbroken, changed. What happened on that trip, and why is it now so important that Camilla puts her own shaky marriage on hold to travel across the world and fulfil her sister’s dying wish?

Starts off a bit slowly, but then hooks you in. A couple of good twists.

Thanks to NetGalley and the publisher for an arc in exchange for my honest review.
