When supermodel Kacy Koska steps into her San Francisco bathroom, death may be waiting. A genetically engineered snake strikes with venom no one, including renowned herpetologists, can identify.

The doctors are baffled. The antidote is unknown. And someone is counting down Kacy's final days with taunting messages.

Los Angeles ADA Matt Sullivan races north to find his fiancée fighting a toxin that's turning her own body into a weapon. Each day brings new outrageous behavior: memory lapses, mental turmoil, and hallucinations.

This snake was no accident-it's the perfect murder weapon, created in a secret lab and delivered by a depraved woman who will stop at nothing to reclaim what she believes is hers. Beautiful, brilliant, and completely obsessed, she orchestrated Kacy's death with scientific precision. Behind her lies a web of international pharmaceutical espionage where stolen research is worth billions and human life is expendable. And the only person who knows the antivenom formula has been silenced forever.

With time running out, Matt makes a desperate gamble: he becomes his ex-lover's prisoner, betting his life that her twisted love might be the key to saving Kacy. But in a world where love and obsession blur, the cure might be deadlier than the disease.

From the foggy streets of San Francisco to a remote Marin County compound where scientists play God, KING MAMBA delivers a page-turning thriller that asks: How much are you willing to sacrifice to save the person you love?

The clock is ticking. The venom is spreading. Death can come in fourteen days. And Matt has one chance to save her.
