Perfect for you if...

You love morally grey protagonists who are funny and lethal in equal measure, like Eve from Killing Eve.
You're after high-octane spy thrillers with European settings, twisting plots, and characters you can't predict.
You want a female-led action series that doesn't soften its heroine or slow down for sentiment.

Maybe not for you if...

You prefer slower-burn psychological thrillers that linger on internal conflict rather than constant motion.
You need likeable protagonists or traditional heroines; Acid Vanilla is neither.
You're looking for romance as a central thread; this is pure espionage with survival at the core.

About this book

Acid Vanilla was a highly skilled assassin—cold, quirky, and brutally efficient. When a routine hit in Paris reveals an explosive conspiracy, her fractured identity begins to unravel. Betrayed by her agency and hunted across Europe, Acid's survival depends on forming an alliance with a hacker she was sent to kill. To stay alive, she must confront the twisted truth of who she really is before the people who created her eliminate her permanently. Final Kill is the first book in Matthew Hattersley's Acid Vanilla thriller series. The story combines fast-paced action with dark wit and emotional depth.
