Leah was wrenched from everything she knew at a young age and turned into a killer. It became that she didn't know anything else but the day's toil of hardening her body and her mind.

Her mentor Caleb was the only person she saw and she couldn't escape him. We only know that at some point they fell in love, but it didn't quite go according to plan.

The present Leah Feltham is now the toughest assassin in London, a woman in her thirties working alone, existing for the job, nothing else.


Then, something goes wrong.


War is brewing. She knows it.

And she's about to find her true love, right before it all kicks off...
