Professor Savannah Selbourne lives on The Raft. The isolated country that was once Great Britain has been free of germs for decades. The plagues are over, the vermin that caused them are extinct. Every billboard brandishes the government's slogan: with sterility comes liberty!
But did the poison ever really go away?
Savannah's new job gives her the opportunity to discover the truth, yet revealing that truth could put her on the wrong side of those in power. How deep will she bury the lies for the sake of her wife and the child they yearn for?
One thing she is sure of: the poison is toxic.
But everyone is safe now ... aren't they?

Six years after the events of The Poison Maker, the oppressive government maintains its totalitarian control across The Raft, and Professor savannah Selbourne is now their pawn. Despite her humble beginnings, she has become an essential voice in the regime. Yet she yearns to break free.
Then, The Raft starts to shake.
Savannah's life is about to implode. She thought she knew how deceitful the powerful are. But the corruption runs deeper than she ever imagined.
With her world crumbling around her, Savannah battles to save her family. But after years of deceit, can she convince her wife to look past the lies? Only Savannah can expose the poison.

Months have passed since the events of The Invisible Kick and The Poison Maker, and Savannah’s fresh start has not been easy. The once infamous food scientist has failed to get the lab working. Food shortages are rife, and she and her fellow Raft citizens are seen as a burden.

But there is no going back. The Raft is mostly destroyed, and Savannah believes there is no one left alive.

Then the satellite phone rings.

A few stragglers, barely surviving need rescuing.

As her new country prepares for its first democratic elections, Savannah must convince everyone that her people are worth saving.

Once again, Savannah finds herself as a political pawn. Only now, the stakes are higher. The clock is ticking. This time, it’s life or death.

Savannah and her family escaped the Raft, but who did they leave behind?
