Victoria is Queen. Charles Darwin’s son is Prime Minister. And steam is the power that runs the world. At 17, Claire Trevelyan, daughter of Viscount St. Ives, was expected to do nothing more than pour an elegant cup of tea, sew a fine seam, and catch a rich husband. Unfortunately, Claire’s talents lie not in the ballroom, but in the chemistry lab, where things have a regrettable habit of blowing up. When her father gambles the estate on the combustion engine and loses, Claire finds herself down and out on the mean streets of London. But being a young woman of resources and intellect, she turns fortune on its head. It’s not long before a new leader rises in the underworld, known only as the Lady of Devices . . . When she meets Andrew Malvern, a member of the Royal Society of Engineers, she realizes her talents may encompass more than the invention of explosive devices. They may help her realize her dreams and his . . . if they can both stay alive long enough to see that sometimes the closest friendships can trigger the greatest betrayals . . .

    What most don’t know—including her sexy new partner, Eli Margolis—is that while Cacy works to save lives, she has another job ferrying the dead to the Afterlife. Once humans are “Marked” by Fate, the powerful Ferrys are called to escort the vulnerable souls to either eternal bliss or unending fire and pain.Unaware of Cacy’s other life, Eli finds himself as mesmerized by his fierce and beautiful partner as he is mistrustful of the influential Ferry clan led by the Charon—who happens to be Cacy’s father. Cacy, in turn, can no longer deny her intense attraction to the mysterious ex-Ranger with a haunted past. But just as their relationship heats up, an apparent hit takes the Charon before his time. Shaken to the core, Cacy pursues the rogue element who has seized the reins of Fate, only to discover that Eli has a devastating secret of his own. Not knowing whom to trust, what will Cacy have to sacrifice to protect Eli—and to make sure humanity’s future is secure?

    That's why he's been hired to descend into the Nightside, an otherworldly realm in the center of London where fantasy and reality share renting space and the sun never shines.
