When her mother recieves a letter delivered to her 50 years late, Edith Burchill begins a quest to better understand her mother and why the letter moved her so. In the process she becomes entangled in the story of a mysterious castle, it's legends and the family that inhabits it, the three Blythe sisters. To say anymore would give away the pure joy and suspense of reading this novel for yourself. 
 This is the 3rd novel of Kate Morton's that I've read and they just keep getting better and better. Morton has a knack for fluidly moving through time periods and characters' points of view to create a suspenseful story that spans generations, usually within the same family. She does a terrific job of developing her individual characters; putting you inside their heads. She also has a knack for making you feel as if you are right there with them, whether it be a sunny day in the garden or a stormy night in the tower of the castle. 
 This book has already garnered many great reviews. I'm glad to add my five stars to the list!
