In Victorian London, driven by steam and fuel, vampires, werewolves and gangs of cutlasses take to the streets at night, and a man made partly of metal discovers what he will do to protect the woman he loves...

After being attacked by a brutal vampire, John "Rip" Doolan struggles to tame his dark desires brought on by a bloodlust virus and believes he has mastered his inner darkness. But there's something that threatens Rip's hard-won composure—Esme, his best friend and the only woman he's ever wanted. If the stubborn beauty understands what he has in mind, their friendship will come to an end...

Six months Esme waited for Rip to recover and make her his personal trell. She doesn't dare hope for anything more and is too afraid to risk her heart, so she becomes desperate when Rip claims that he never wanted to lay claim to her.

But when a brutal gang of cutlasses starts killing on the right and left in Whitechapel, Rip and Esme have no choice. They must understand how deep the passion burns between them and take their relationship to the next level...or risk losing each other forever.
