He Doesn't Kiss. You're Taken.
Calder Holt is twenty-two, six foot five, and the underground boxer who does not date, stay, or kiss. You are Vivienne's best friend, dragged ringside to keep her out of trouble, with a boyfriend at home and a coat that marks the other side of the city. He has already decided you are a spoiled thrill-seeker. Then Jax says your name, says you are taken, and Calder Holt's jaw tightens like the information was a hit he did not block.


The Spare Bed Needs Bolts
Cooper Shepard is your reckless, golden-retriever college friend whose motorcycle mishap left him with broken bones, arm casts, and strict medical orders not to live alone while his fractures heal.

He flashes an apologetic grin and begs for help with the bolts. Let him in, or lock up.


The Key Is on Your Neck
Rory Crowley is the cocky college star who drunkenly boasted at a frat party about his self-control, wagering he could wear a chastity device without breaking.

He grips the doorframe and demands you name your price for release.

Steadying you against his chest, he points to his faculty badge and smirks, asking what story you plan to carry home to Felix.

Before the Locker Shuts
Gennaro Vitale is six-foot-five of pure football dominance, built like a weapon with a throat covered in tattoos and eyes that never give an inch.

Say what you came to say, or fold the sign and let him walk away.

Do Not Cheer That Kiss

Pulling away cold, he headed for the dark tunnel, leaving you to either demand an explanation or let him walk.


That Sweater Comes Off Tonight

The Typhoon Took His Excuse to Leave
Darian is your private tutor, calm and careful with the line between a lesson and a want, and you are twenty-one with your parents overseas. A typhoon arrived earlier than the forecast.

The house is empty except for the two of you.

Stepbrother's Bad Friend

Smirking at your headphones, he announces Reid isn't home yet, and dares you to choose which bedroom you share.


Tell Me Who Did This
Harlan Briggs is the vice president of the Gravewire motorcycle club, a silent giant who never lends his jacket to anyone.

Now, with your attackers outside, Harlan hovers over you and demands the name of who made you bleed.

He finds you, a 29-year-old former Spetsnaz operative, alone in their torn field tent and wearing one of their jackets. Your pistol is on his side of the cot; his men are outside in the storm.

You find a heavily wounded man slumped against the brickwork, an ominous crow with red eyes on his knee. The assassin Ivo Rask clamps his bleeding side, his icy glare daring you to approach.
