He was her sister's fiancé. Now he's her husband. And someone is lying about how her sister died.

When Ava walks down the aisle, she's not just marrying the perfect man—she's stepping into her sister's grave.

Noah is charming, devastatingly handsome, and dangerously unreadable. His vows were flawless. His touch makes her melt. But every kiss tastes like a lie.

Because Lily—Ava's sister—is dead.

Everyone says it was an accident. Everyone says to move on. But Ava has Lily's journal. And one chilling sentence keeps repeating in her mind:

"He won't let me leave."

Now, Ava must play the part of the grieving bride. She must smile, obey, and sleep beside the man who might be a killer. She thought uncovering the truth would be the hard part.

She didn't know surviving it would be even harder.

For fans of Verity, The Last Mrs. Parrish, and Gone Girl—a dark, addictive spiral of betrayal, obsession, and one jaw-dropping twist after another.
