One Night. No Alibis. When Sienna Cross leaves a house party alone and is found dead hours later, everyone has a story. Nobody has an alibi. Ava Monroe noticed things that night that nobody else did: the tension in Sienna’s posture, the phone calls taken in private, the fear behind the practiced smile. Now, with the police asking questions and the friend group’s answers already failing to match, Ava finds herself pulling at a thread that unravels everything. What begins as a search for the truth about one night slowly becomes an excavation of months of hidden history. Sienna had been watching all of them, building a journal full of secrets, leverage, and carefully dated observations. She knew things about each of them that they had never meant for anyone to know. And she had been planning, after the party, to use what she knew. The deeper Ava digs, the more the line between victim and player blurs. The friend group fractures under the pressure of what they knew, what they did, and what they chose not to say. And at the center of it all is a question that grows more uncomfortable the closer Ava gets to answering it: did someone set out to hurt Sienna, or did the weight of everyone’s silence finally collapse on its own? Sharp, tense, and emotionally grounded, “One Night. No Alibis.” is a teen thriller about the secrets that live inside close friendships, the difference between staying quiet and telling an outright lie, and the cost of a truth that arrives too late to save anyone.​​​​​​​​​​​​​​​​
