It's Lydia's last chance to stop the Montauk Project...or else be lost in time forever.

Lydia has been trained into a person she might have once feared: focused, fierce, deadly. Although she never wanted the life of a Montauk Project recruit, the Project has captured someone she loves-someone she'll do anything to save.

Then Lydia glimpses a world in which the Montauk Project never existed. The Project has taken so much from Lydia already, but she knows that she will sacrifice everything to make her vision of a world without the Project a reality.
