Join Artemis and her band of misfits as they travel through time doing the bidding of the all-powerful Faculty.

Timeless enemies. Timecrossed lovers. A future in freefall . . .

Artemis has just graduated top of her Cambridge class of assassins, the most respected discipline in the Faculty's army. As a timeless soldier, she will travel in and out of linear time, protecting the fragile future with her lethal hands. Along with her crew - a navigator, an armourer, a historian and a physician - Artemis will do whatever it takes to stop the destruction of history by dangerous time vandals. The crew's assignments will have them dancing through the ballrooms of Regency Bath, infiltrating spy networks in the 2050s, climbing the barricades of 1830s Paris and frequenting Space Age speakeasies.

Artemis might look like she's got everything she ever wanted, but growing up in Cambridge hasn't been easy. Assassins must be ruthless to survive and she's made enemies amongst her peers, discarded a fair few lovers and has a secret that could lose her everything she's worked for. And things don't get any simpler once Artemis and her crew start to travel. On assignment, all timeless soldiers must obey four fundamental rules:

Never betray the Faculty
Never let a time vandal live
Never fall in love with a target
Never die in linear time

But Artemis is going to meet a time vandal who has been waiting for her. And despite knowing this man is devastation distilled-that he is the very war she is fighting-Artemis is going to break all the rules and let him live. As he follows her through time and space, Art is going to become obsessed with two questions: why is he so determined to be everywhere she is? And why can't she bring herself to kill him?
