Detective Erin Halstead thought she was investigating an isolated murder. Now, she's thrust into a race against time to uncover the origins of a living, evolving organism that excretes deadly toxins, grows faster than wildfire, and defies every attempt to destroy it. As the slime spreads across the coast, devouring ecosystems and igniting public panic, humanity faces an unimaginable question: how do you stop something that only grows stronger with every passing moment?
From the lab to the ocean's depths, from the Salk Institute to the halls of power, Halstead must navigate a web of secrets, conspiracies, and scientific hubris to find answers-before the world itself succumbs to the bloom of death.
For months Summer is trapped in a cellar with the man who took her - and three other girls: Rose, Poppy, and Violet. His perfect, pure flowers. His family.
But flowers can't survive long cut off from the sun, and time is running out...
