The Book of Leo (Zodiac Killers #3) Release Date: September 29, 2026

Published

I don’t fear monsters. I hunt them.

By day, Dr. Zara Nightingale is a senior biochemist at DSTL – overlooked, underestimated, and dismissed as the pretty blonde in the room.

By night, she becomes Leo, one of the Guild’s deadliest Zodiac assassins.

Seductive. Theatrical. Traceless.

Her first mission is simple: eliminate a modern-day Jack the Ripper who has terrorised London for years.

Her second mission is not so easy.

She’s ordered to eliminate a corrupt politician whose power reaches far beyond the UK – into boardrooms, governments, and blood-soaked back channels across Europe.

Everything fractures the moment she crosses paths with:

Fox – the infuriating, cocky Guild assassin sent to monitor her every move.

Elias – the soft-hearted son of her target, who sees past her masks and makes her hesitate.

Cole – the elegant right-hand man of her target who looks like a villain but may just be her most dangerous ally.

Three men.

Three threats.

Three obsessions.

When a conspiracy inside the Guild rises to the surface, Zara must decide who to trust, who to love…

and who to kill.

But the lioness doesn’t bow.

She hunts.

And this time, she isn’t hunting alone.

~~~

The Book Of Leo is a dark reverse-harem assassin romance with high tension, steamy chemistry, and a guaranteed HEA.
