Frequently Asked Questions

What is "How to Kill Your Rival" about?

From dark romance sensation Effie Campbell comes the next addictive instalment in her steamy and stabby dark romcom series

Those who slay together… Stay together.

As the heir apparent to the Death Council – a secret organisation of elite contract killers – Eliza Hamilton is fighting to prove herself in a room full of men who'd rather take advice from a corpse than a woman.

Then someone starts sabotaging her kills.

Her targets keep turning up dead before she can get to them, damaging her reputation and making her look incompetent.

Her prime suspect is her new stepbrother, James Rutherford: an infuriatingly gorgeous professional pain in her arse, and her biggest rival. Also one of the few people alive skilled enough to pull it off.

But when a far deadlier threat emerges, Eliza and James are forced to do the unthinkable: work together.

As the body count rises, so does the tension between them. Between the arguments, the sabotage and a shared enthusiasm for creative homicide, an inconvenient attraction begins to spark. One built on competition, mutual respect, and entirely too much eye contact over dead bodies.

But solving the mystery means getting closer than either of them would like, and the line between rivalry and obsession is becoming harder to ignore. After all, there's a fine line between wanting to kill someone...

...and wanting to kiss them.
