On the eve of World War II, a honeymoon turns treacherous.
For Stella Bled Lawrence, being wealthy and stylish in 1938 is exactly what it's cracked up to be. She's blissfully unaware of the rising tensions in Europe even as she travels to Vienna on the eve of the Kristallnacht, The Night of Broken Glass. Stella and her husband, Nicky, witness the night's atrocities first hand. Even as they watch the horror, they never imagine it will touch them personally, a pair of wealthy Americans on their honeymoon, but touch them it does. In the chaotic aftermath, Stella finds passion and purpose in the form of a package with a Paris address. She promises to deliver it, not knowing what it contains or who wants it. Soon Stella must decide who and what she's willing to sacrifice to keep a secret that has been quietly guarded for five hundred years.
