About the Book

#1 Bestselling Regency Romance on Amazon and Barnes & Noble

A former spy with dangerous secrets fears nothing…except his dark desire for the delicate virgin he cannot have. 

A Prisoner of His Past
Gabriel Ridgley, the Marquess of Tremont, is dubbed The Angel for his pristine reputation. Yet he harbors a dark secret: a spy during the Napoleonic Wars, he bears deep and dangerous scars. When he meets Miss Dorothea Kent, a delicate virgin, he is torn between carnal desire—and the need to protect her from his inner demons.  

A Captive of Her Passions
Despite a frail constitution, Thea Kent has strength of spirit and heart. A wild attraction blooms between her and Gabriel, a widowed aristocrat with tortured eyes, yet he resists the pull between them. When fate places his disabled son in her care, she’s determined to guard the boy—and unravel the mystery of Gabriel’s past.

Freed by Love and Passion
Someone is killing Gabriel’s former colleagues, and he may be next on the list. As the desperate hunt for the villain begins, he and Thea get entangled in intrigue, betrayal, and desire too powerful to resist. Will trust help them to survive… and true love set them free?

“I discovered a new auto-buy author…I’ve now read each of Grace Callaway’s books and loved them – which is exceptional. Gabriel and Thea from this book were two of the best characters I read this year. Both had their difficulties and it was charming to see how they overcame them together, even though it wasn’t always easy for them. This is my favourite book of 2015.”

– Romantic Historical Reviews

“The romance between Gabriel and Thea is really hot. The two of them have a great chemistry and the scenes between them burn up the pages.”

– Sheila, Goodreads

“Another sensual, suspenseful, delightful, seriously HOT read by Grace Callaway. Dear Lord, lady, I did a lot of fanning, sighing, and smiling while reading this book…I can’t wait for the next one. GIMME!”

– Jackson, Goodreads

“Thea was everything you hope for in a heroine. Her delicate constitution does not hold her back from being a strong, spirited and intelligent woman. Gabriel, despite being widowed and having his own demons to tame, is her perfect mate and their chemistry is explosive.”

– Lily, Goodreads

“Another awesome installment in the series. This book is filled with all the makings of the kind of romance I enjoy- intrigue, charm, strength, sex, and romance. The main characters are well-matched, having their own demons to counter and I love seeing the rest of the characters from the previous books all come together.”

– Lori, Goodreads

“What I can tell you about is her ability to flawlessly flow the plot….a novel in her hand is like a AMG GT in the hand of a good driver….no bumps, or swerves, or jerky breaking…just one smooth ride lol. The intimate scenes in the hand of any other author would come off vulgar and cheap…but Callaway immerses it in so much love, and passion, and longing, and angst that you can’t help but respond. I still skim read them (with a flushed face lol).”

– Gilgamesha, Goodreads

“Lard Tunderin Jaysus is this book ever brilliant, and it most definitely is one of the best books I’ve read this year so far….The suspense, the intrigue, the whodunit to the most sensual decadent intimacy between Gabriel and Thea (absolutely smoking hot)…will keep you riveted to this book.”

– Patricia, Goodreads

“I can’t say enough great things about this book!! The second book in the series was just as great as the first. I have very few authors that I read that I can say I enjoyed every single book they wrote. Ms Callaway is one of them if not the best of them. I can not wait for the next book in the series. I have also read all of the books in the series mayhem in Mayfair. All were 5 stars as well.

– Mary, Goodreads

“Grace’s books are truly among the best historical romance books around and she certainly didn’t disappoint with this one either. It had me captivated from the beginning with a hot alpha and dark sensual promises; all mixed in with romance and a gripping mystery.”

– Nicola, Goodreads
