This cli-fi novel from a notable archaeologist and anthropologist explores a frozen future where archaic species struggle to survive an apocalyptic Ice Age One thousand years in the future, the zyme, a thick blanket of luminous green slime, covers the oceans. Glaciers three-miles-high rise over the continents. The old stories say that when the Jemen, godlike beings from the past, realized their efforts to halt global warming had gone terribly wrong, they made a desperate gamble to save life on earth and recreated species that had survived the worst of the earth's Ice Ages. Sixteen-summers-old Lynx and his best friend Quiller are members of the Sealion People—archaic humans known as Denisovans. They live in a world growing colder, a world filled with monstrous predators that hunt them for food. When they flee to a new land, they meet a strange old man who impossibly seems to be the last of the Jemen. He tells Lynx the only way he can save his world is by sacrificing himself to the last true god, a quantum computer named Quancee.

This second book in a cli-fi series from a nationally-recognized anthropologist explores a frozen future where archaic species struggle to survive an apocalyptic Ice Age In the brutal Ice Age caused by the ancient Jemen war, many archaic human species, including Denisovans and Homo erectus, hover on the verge of extinction. There seems no way out, until the greatest Neandertal holy man, Trogon, has a vision. Legends say the truce that ended the old war left one hostage in the hands of the victorious rebels: the godlike Jemen leader known as the Old Woman of the Mountain. According to Trogon's vision, only one person knows the location of that burial cave. Trogon must capture young Quiller and force her to lead him there...for the Old Woman may not be dead. She may only have been in stasis for a thousand summers, and when reawakened she will save them from oblivion. But according to the Denisovans—Quiller's people—Trogon is the most powerful witch alive. He's up to something evil that will surely spell their destruction. He must be stopped before it's too late. Quiller's best friend Lynx must brave towering glaciers, dire wolves, and prides of giant lions to save her and stop Trogon.

This third book in a cli-fi series from a nationally-recognized anthropologist explores a frozen future where archaic species struggle to survive an apocalyptic ice age. It’s been 925 summers since the Jemen introduced zyme, a bioluminescent algae, into the world’s ocean and unwittingly triggered an ice age that has consumed most of the planet. All but a handful of Jemen flew to the stars, but before they left, they recreated several extinct species that had thrived in the last ice age. After almost a thousand summers, the archaic hominins that struggle along the edges of massive glaciers are dwindling. All they have to save them is a dying quantum computer called Quancee and her student, a Denisovan man named Lynx. When the last Jemen, Vice Admiral Jorgenson, tells Lynx he’s going to dismantle Quancee and use her parts to create a new computer, Lynx is stunned. But while Lynx battles to save Quancee, the quantum computer has other priorities. Before she dies, she has to save a special boy who cannot save himself. Meanwhile, in the lodges of the Sealion People, a sick boy on the verge of manhood hears voices, including an old woman who sings to him. When Jawbone goes on his first quest to find a spirit helper, that same old woman finds him, and his life will never be the same.
