The Poison Maker

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?
