The sisters' names (Faith, Hope and Charity) were a bit twee but apart from that I liked this book a lot. The story starts in 1977 and goes back and forth to 2016 (yes 2016). Gradually the tale unfolds and everyone's secrets are revealed. A very enjoyable book with great descriptions of submerged forests, diving, different locations, interesting characters - plenty to keep you turning the pages. Definitely one for the suitcase, something to keep you engrossed whilst sun bathing.
