A sick boy, barely alive. An old doctor, sentenced to die. A single mother, with a baby to hide. An outcast girl, determined to survive. And a tiny kitten, bioengineered to save their lives. One million years in the future, an isolated human society clashes with an ecosystem evolved beyond their intelligence. Faced with apocalypse, it's only human nature to hope for a miracle. Catastrophically subversive, Petrichor shifts chameleonic: It's a million-year-old sci-fi about the end of the world; a family saga of warring generations; a classic tale of synthesis versus disintegration; an invitation to fall in love with what you fear.
