'A top-notch thriller ... Intriguing, exciting and enthralling.’ Liz Nugent

---

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?

Really enjoyed this book, was gripped from the start!
Wanted to know who the killer was. Loved the concept of what Alice was doing with the dating app. It really would make the dating world alot safer.

Thanks Netgalley for letting me read this book for an honest review

Alice runs her own company, Cygnus, which operates a popular dating app in a market that is shrinking fast, as people become increasingly disenchanted with such approaches to romance.

Almost nobody knows that one of the reasons Alice has chosen to start this business is that her own past trauma - stemming from intimate partner violence - has led her to secretly incorporate an algorithm that allows Cygnus to weed out potentially harmful male users. And Alice herself has a highly unconventional system of checking out the veracity of the algorithm.

Now though, one of those problematic male users has been found murdered, and Alice's own brother is the investigating police officer on the case. And whoever killed the man has threatened to expose Alice's algorithm use if she does not publish a list of the men that Cygnus has already privately identified as being a possible threat to female clients. How far will Alice go to protect what she has built?

This is a gripping story and one that is based on a very creative premise. I really enjoyed it, and I think most thriller readers will, too.
