An Unnatural Vice

Book 2, Sins of the Cities

This book can be downloaded and read in iBooks on your Mac or iOS device.


In the sordid streets of Victorian London, unwanted desire flares between two bitter enemies brought together by a deadly secret.

Crusading journalist Nathaniel Roy is determined to expose spiritualists who exploit the grief of bereaved and vulnerable people. First on his list is the so-called Seer of London, Justin Lazarus. Nathaniel expects him to be a cheap, heartless fraud. He doesn’t expect to meet a man with a sinful smile and the eyes of a fallen angel—or that a shameless swindler will spark his desires for the first time in years.

Justin feels no remorse for the lies he spins during his séances. His gullible clients simply bore him. Hostile, disbelieving, utterly irresistible Nathaniel is a fascinating challenge. And as their battle of wills and wits heats up, Justin finds he can’t stop thinking about the man who’s determined to ruin him.

But Justin and Nathaniel are linked by more than their fast-growing obsession with one another. They are both caught up in an aristocratic family’s secrets, and Justin holds information that could be lethal. As killers, fanatics, and fog close in, Nathaniel is the only man Justin can trust—and, perhaps, the only man he could love.

Praise for An Unnatural Vice

“Explosive.”Publishers Weekly

“Animosity and attraction surge in equal measures when Nathaniel Roy, investigative journalist, faces off against Justin Lazarus, the Seer of London. Their opposing vocations and radically different backgrounds create a powerful and fascinating conflict. Although this book can be read as a stand-alone, [K. J.] Charles continues to build tension and add menace by deepening the overarching mystery introduced in the first novel. The series is definitely building to a firecracker conclusion.”RT Book Reviews

An Unnatural Vice is a well-developed, entertaining romance that left me breathless. . . . Keep these historical romances coming, Charles!”—The Book Corps 

An Unnatural Vice is a tremendous follow-up to the first book in the Sins of the City trilogy. Fans of the series—and of K. J. Charles—will love the romance between Nathaniel and Justin, and the Taillefer family mystery. . . . An Unnatural Vice is exciting, entertaining, romantic—and wonderful.”—All About Romance

“A real tour de force. The mystery of the missing Taillefer heir is smoothly and skillfully woven through Justin and Nathaniel’s love story and the ending brilliantly sets up the next book. . . . The real heart of the book is the complicated, messy but glorious romance between two bitter enemies. An Unnatural Vice is a must-read and I can’t recommend it highly enough.”—Romantic Historical Reviews

An Unnatural Vice is a thrilling, achingly romantic story. Nathaniel and Justin have both undergone serious trauma in their lives, and Charles digs into their respective psychologies with piercing insight. . . . With expertly paced action sequences and the evocative setting of fog-drenched Victorian London, An Unnatural Vice is the rare historical romance that is both transportive and immediate.”—BookPage

Customer Reviews

And then came love

I received an advance reader copy in exchange for a fair review. The story of Nathaniel and Justin working together to find the rightful heir to the Earldom turns into a love story between the two men. The book has intrigue, danger and humor. The only problem I have with the book is the fact that is has a cliffhanger. I prefer books that are self-contained. Other than that, it is a good read.

Character flaws a plus

KJ Charles has written sizzling gem. Her dalliances into the underworlds of Spiritualism and odd cults add deliciously to an unfolding mystery and blossoming romance. A delightful read begging for continuation.
