In 13th century Japan, a land of ancient spirits, shapeshifting animals, and demons, Ken'ishi is a warrior without a master. Orphaned in infancy, he has only one link to his past - Silver Crane, his father's sword. When Silver Crane is stolen, Ken'ishi must go on a quest to recover his very identity. The crime lord known as Green Tiger holds the key to Ken'ishi's past. With intrigues stretching to China, where the Mongol emperor Khubiliai Khan builds an invasion fleet, Green Tiger knows of Silver Crane and dreams of the day when he can destroy the shogunate and restore his shattered clan. With a wooden sword as his only weapon, Ken'ishi descends into the shadowy world of flesh houses, Chinese smugglers, and Mongol spies. To succeed and unleash Silver Crane's power, he must face the darkness in his own soul.

Mad science, friendship and betrayal, Black Sand, politics: the Artifice Academy is a hard place: every moment a lesson, every lesson a trap. Inga dares to hope, walking a tightrope of isolation between failure and madness.

Hark is a timid, pacifistic Viking with a love for all living things inspired by watching PETA documentaries. Crone is a vintage Schwinn road bike and a bit of an outcast himself, but it's not his fault who his rider is. Something has to change before the Elder bicycle and Orr, the Viking leader, throw them both out with the spare parts. A century after Fukushima and the toxic sea, Harek and his mind-beaming bicycle must prove themselves in a world where everyone (and every thing) is out to get them. Including Alec Baldwin.
