Filled with possessive alpha heroes, mafia intrigue, sizzling romance, and unforgettable chemistry, this dark contemporary romance is perfect for readers who love morally gray characters and high-stakes love stories.

Val has spent most of her life feeling alone.

After losing both of her parents, the only family she has left is her powerful half-brother, who keeps her safe through The Alliance. Protected by bodyguards but longing for genuine love, Val never expects a chance encounter at the airport to change everything.

Then she meets Dom.

For Dom, family and loyalty come before everything. Raised in the mafia, violence is a way of life, and when tragedy strikes his organization, he realizes he'll need powerful allies to survive the coming war. Joining The Alliance becomes his only option—even if it means risking everything.

As danger closes in and enemies threaten those they love, Val and Dom discover that trust comes at a price, and love may be the most dangerous gamble of all.
