Here's a good story to add to your Summer reading list: The Forgotten Garden by Kate Morton.
It's the thoroughly engrossing story of a small child who is seemingly abandoned by her family at age 4, and spends a lifetime trying to reconstruct her personal history.
The mystery unravels across continents (England, Australia), decades, and generations of descendants who piece together clues from old scrapbooks, old friends, and some good old-fashioned sleuthing.
A lively, twisting plot keeps you turning the pages to the end, with the chapters rotating between the perspective of the small child who has grown up, her doting granddaughter, and the chapters of a book of children's fairy tales that hold the secret to her past.
The book itself is like a fairy tale, and is reminiscent of Frances Hodgson Burnett's The Secret Garden, which was one of my favorite books as a child.
Kate Morton is a fantastic storyteller; you'll feel transported between 1913 London, 1975 Brisbane, and present-day Cornwall - with detailed, period characters and landscapes all along the way.
Disclaimer: I received a complimentary copy of this book from the Altria Books division of Simon & Schuster as part of their promotional outreach, but that has not colored my review of the book - I really enjoyed it.
