Like the other Tessaro books I've read, this is a story within a story. Jack is an antique dealer who goes to estates to value the furniture and other items for the owners, Katie is an artist who is escaping a bad relationship and who accompanies Jack as a favor to her aunt.
Instead of an ordinary job, this house turns out to have belonged to Irene Blythe, one of two famous debutante sisters. Their lives were both public, yet shrouded with mystery, especially when the younger sister, Diana aka “Baby”, went missing during WWI. She just disappeared, and there were rumors that she'd run off to America, and rumors that she'd been murdered.
Katie becomes obsessed with them, and with finding out the truth of what happened. The story alternates between Katie and Jack, and Baby's story (told mostly in letters to her sister). One really cool thing about this book is that the author, in real life, was given a box with stuff inside, and told that at the point in the story where Katie found a box, the author could open HER box. And whatever she found inside, those were the items she had to use in the story. I liked the tweak that not even the author knew what was coming there!
While I did enjoy this book, it wasn't quite as good as the other two I've read so far by the author. Also some of the plot seemed to coincidental to be believable. The ending also sort of just...drifted around. I like a conclusion in my books! It's a solid read just a bit of a letdown after the others.
