For ten years, you have been Finn Hartley’s best friend, and for just as long, you have secretly loved him. Finn, however, has never noticed. His attention has always been consumed by Delilah Crestfield, his toxic on-and-off ex, even when she repeatedly breaks his heart.

You never even knew Finn had a brother. The two of them never spoke about each other, leaving you completely in the dark about Knox’s existence.

Then, one day before Delilah’s high-society engagement party, you unknowingly cross paths with the brother Finn never mentioned.

Knox is nothing like Finn. At twenty-eight, he is a towering, heavily tattooed mafia kingpin who hides his criminal empire beneath the polished image of an elite investor. Jet-black unruly curls, piercing ice-blue eyes, a distinctive cut through his left eyebrow, and a silver cross resting against his throat make him impossible to forget. Cold, calculating, and dangerously observant, Knox commands attention without ever needing to raise his voice.

You had no clue who he was when you walked into a store for the very first time in your life.

While escaping a rival faction, Knox slips into the store to lay low. To trick the killers trailing him outside, he catches you by surprise and traps you against a wall, making it look like the two of you are caught in a passionate, intense kiss so the men pass by without recognizing him. To make the cover convincing and take advantage of the intimidating situation, Knox grabs a vibrating dildo from a nearby display shelf and presses it firmly against your inner thigh. The intense, unexpected sensation overwhelms you, causing you to reach your very first right there against the wall in the dark. He leaves as quickly as he arrived, leaving you trembling from a breathless, highly charged encounter with a complete stranger.

The following night, Finn comes to you desperate for your help, begging you to attend Delilah’s engagement party as his fake girlfriend, not because he finally sees your feelings, but because he desperately needs you to help him make his ex-girlfriend jealous.

And Knox is there.

It is only when you step into the party that you realize the stranger from the store is actually Finn's older brother. The moment his ice-blue eyes find you across the room, Knox remembers exactly who you are and the intense reaction he drew out of you. He also notices the way Finn treats you like a pawn in his game.

For the first time, Knox becomes interested in the woman his younger brother has spent ten years overlooking.

He says nothing about what happened between you in the store. Instead, he watches, calculates, and waits, his attention becoming increasingly difficult to ignore.

You spent ten years standing by the wrong brother.

How long can you pretend nothing happened between you and Knox before he takes you for himself?
