The Poison Daughter by Sheila Masterson (Pre-Order August 18, 2026) 

A deadly kiss. A cursed marriage. A romance that could destroy them both.

Perfect for readers of romantasy, enemies-to-lovers romance, and dark fantasy romance, this addictive standalone follows a poison-lipped assassin forced into an uneasy marriage with the only man immune to her deadly kiss.

Every person Harlow Carrenwell kisses dies instantly—and she's spent her life making sure dangerous men have every reason to fear her. As the youngest daughter of Lunameade's powerful magical founding family, Harlow serves as their assassin, eliminating anyone who threatens their rule.

But behind her family's back, Harlow leads a dangerous double life as a vigilante, targeting abusive men throughout the city's shadowed streets.

Her newest assignment should be simple: marry a mysterious stranger and kill him.

There's just one problem.

Henry Havenwood survives her kiss.

Now trapped in a marriage with the one man she can't kill, Harlow must uncover why the long-vanished Havenwood family has suddenly returned. As deadly secrets, ancient magic, and political conspiracies unravel inside a fortress surrounded by vampire-infested woods, Harlow faces an impossible choice: protect her identity as a killer—or let herself fall for the one man who knows exactly who she is.

This deluxe limited first edition includes sprayed edges, a full-color illustrated case, and an exclusive bonus chapter from Henry's point of view.
