Paris, 1954. Eli Cole, American attaché, wants only one thing: to avenge his wife's murder. But the trail has gone cold. After two years, drinking to his beloved Liana's memory is all he has left - until the secrets she took to the grave come back to shatter them all. A hidden photo, a Gestapo file, an unsent letter: these are some of the clues Eli must piece together if he is to understand Liana's secret life, and her mysterious mission. But the clock is ticking. Powerful new enemies are out to give Eli a one-way ticket back to the United States - in a pinewood box.

With the help of Liana's father and sister, an old war buddy come abroad, and a cunning teenage girl, Eli unravels the events that led to his wife's death. But getting justice won't be easy. The more Eli reveals of Liana's secret past, the more his devotion to her is tested by her deceit. Can Eli allow himself to recognize the entirety of the woman he married? Will Liana's last art piece, a spectacular glass tree, give Eli the assurance he needs to continue believing in the sanctity of love?

The Glass Tree is a fast-paced, unpredictable mystery, and it is also the story of one man's attempt to untangle the complexities of betrayal, love and forgiveness.
