Lease Mottle practices michemistry, a form of magic. He is loyal to the goddess Hecta, loves Lady Heloniss, and cares for his family estate. But fanatic muddyed from a rival cult have come to Prosper Isle seeking the lost ancient books of wisecraft. Mottle beats them to finding the Blue Book of Knowledge, setting off a race among the cults to also find the Red Book of Power and the Black Book of Foresight. Though a scholar and an herbalist, Heloniss doesn't understand the book or wisecraft, even though she is wrongly suspected of also being a practicer of wisecraft. She must flee persecution and use her wits as she is hunted by muddyed and Kadge Goodfellow, whose skills as a spy may kill or save her. Can she and Mottle safely bring the Blue Book's wisdom to its origin in the Uplands? And will she marry Mottle as everyone expects, or will she choose the dangerous Goodfellow instead? The Blue Book of Wisecraft blends elements of fantasy, science fiction, romance, and the flavor of Shakespeare's dialogue. It is the first in "The Three Books of Wisecraft" series, which continues in The Red Book of Wisecraft and concludes in The Black Book of Wisecraft.
