Henry Flamel has spent his life searching for the family that left everything behind to save him. Now, older and nearing the end of his days, he's followed their trail to a desolate research base carved into volcanic ice caves—the last place his parents were seen before their silence became permanent.

His only tools are the unstable alchemical research they left behind. As Henry experiments, each reaction edges him closer to the truth of what happened here. But something else has already claimed this space, and it is drawn to his work just as desperately as he is.

Uncover your family's legacy, master the dangerous science that defines it—but be warned: the deeper Henry's research takes him, the more he may wish he had simply succumbed to his illness.
