Initiation Night: One Night. Four Men. No Safeword.

She signed the contract at midnight. By sunrise, she couldn’t remember why she’d wanted to leave.

Wren Castillo is a scholarship kid with $47 in her bank account, a mother drowning in medical debt, and a five-year plan taped to her dorm wall in color-coded sticky notes. She doesn’t believe in miracles. She believes in math.

The math says yes.

The Brotherhood of the Obsidian Key — three centuries old, members in the Senate, the Supreme Court, and every building on campus with a name carved above its door — has never initiated a woman. Until now. One night. Twelve hours. Four senior members. Survive, and everything changes: the scholarship, the debt, the future she’s been clawing toward since she was sixteen.

She walks into that chamber expecting an endurance test.

She doesn’t expect Xavier’s hands on her jaw, holding her like a question he already knows the answer to. She doesn’t expect Marcus — the senator’s son, all charm and zero truth — to crack open in front of her like he’s been waiting for someone worth being honest with. She doesn’t expect Theo to watch her like data and then do the one thing she can’t calculate. She doesn’t expect Julian’s mouth on her wrist, shaking — the tremor of a man who just broke three centuries of protocol for a girl he met five minutes ago.

Twelve hours. That was the deal.

Nobody told her about the part where she stops wanting to leave.

The Brotherhood has enemies. Someone was watching through the glass. And Wren Castillo — the girl from Riverside who irons her blazer with a flat iron — just became the most dangerous woman on campus.

Initiation Night is book one in the Brotherhood of the Obsidian Key series — a dark why-choose romance with steamy content, secret society intrigue, and four morally complex men who weren’t supposed to fall. For readers 18+. Ends on a cliffhanger.
