She has a secret. They're using it to kill.
No one knows Alice Keane's dating app is coded with a hidden algorithm to identify men's red flags and hide their profiles from female users. Haunted by her abusive ex, Alice is desperate to protect other women the way she wishes she'd been protected.
But then men Alice's algorithm has identified are found murdered at chilling crime scenes staged to match their red flags. And the killer says they won't stop unless Alice releases the full list of dangerous men to the world.
Knowing she must protect her company, Alice and her hacker friend enter a race against the clock to find out who hacked her app and identify the murderer, all while being pulled deeper into the killer's twisted game of revenge.
How far will Alice go to keep her secrets safe?
