Flight of Fate by Trisha and Nathan Goyer

Book 2 of The Clockwork Chronicles

Summary: 

When destined for destruction, fate must be challenged.

Curator Dante Ramono must remove the priceless Farnese Cup from its hidden vault in the Museo Archeologico Nazionale di Napoli to protect it from Allied bombing. A swift betrayal places the cup in Nazi hands, but not before it reveals its mystical powers. To recover the cup, Dante must join forces with cunning Theodora. Can he trust her, or will he be deceived once more?

In Prague, Kateřina Dubová works to care for the Jews she’s hidden. In her hour of greatest need, her trusted friend, Josef, has seemingly vanished. Danger closes in, yet an unseen protector steps in again and again. Could it be Josef, hidden in the shadows?

The clock is ticking. Is the future set in stone, or can courage and faith change history? Together, these four unlikely guardians must defy the odds to stop the Germans' dark ambitions or risk their very souls.

Betrayal, sacrifice, and destiny collide as unlikely heroes race to save a world at war from the power of a mystical relic.
