Synopsis

She loved him first. He’ll fall for her last – and hardest.

In the shadows of the city he rules, Dahlia Ferrara has spent years in love with one man: Mikail Morozov. Her brother’s best friend. The underworld’s coldest king. The forbidden obsession she was never meant to touch.

He rejected her once.
Now she’s done waiting.

Dahlia offers Mikail ten days – no strings, no future, no promises. On day eleven, she walks away to build a life far beyond the brutality of their world and the secrets that have scarred them both.

But being this close to her, is a crack in his armor he can’t afford.
Forced proximity ignites jealousy, desire, and a control he’s been breaking for years.
Because Mikail has a secret of his own –
he’s been celibate because no one has ever been her.

She’s sunshine in a violent world.
He’s a king built from regret.
And their connection is one line that was never meant to be crossed.

Loving her is betrayal.
Keeping her is war.
But letting her go would destroy him.

A dark, intoxicating forbidden-love mafia romance featuring a jealous, possessive hero, a tortured heroine, forced proximity, unrequited turned devastating love, emotional scars, a celibate anti-hero, and a secret relationship that could get them both killed.

I love books! I have been reading for as long as I can remember. I was the kid with the flashlight under the covers reading until the wee hours. Books were my refuge. I was delighted to discover tree climbing. I would take a book and climb to the top of a Mimosa tree and read for hours...and of course ignore my mother calling for me to do chores. I was committed to reading all of the Nancy Drew stories. Ned was my first book boyfriend. When I was in my early teens I discovered Harlequin romances. I feel in love and it changed my life. I was in love with Love 💕 That’s something for a girl who hadn’t been kissed yet. When I read “he thrust his throbbing member into her womanhood” I was lost to discovering more about this particular brand of romance. But I don’t just enjoy romance reads. My father-in-law introduced me to the high fantasy genre and I loved it. When I bought my first Nook the world of books really took me by surprise. I was enthralled with all the available genres and to my delight I discovered erotica. In most cases, I was with family on visits to bookstores and you don’t peruse those even if they carried them. Oh the shame of it! ;) Thanks to Nancy Drew I still enjoy mysteries along with romance, fantasy, erotica, paranormal, steampunk, thrillers, and well, most anything except a horror of a horror. My favorite might be romance suspense but it’s hard for me to pick just one. I had a serious health issue a few years ago and was forced to quite working after building a career I could be proud of. It was devastating and depressing. I lost myself in books and now spend my days (and nights) reading. I am so appreciative of authors and the wonderful storytelling I’ve found in books. It takes me away from my troubles and introduces me into a world like no other. I love books!
