Veycosi, in training as a griot (an historian and musician), hopes to sail off to examine the rare Alamat Book of Light and thus secure a spot for himself on Chynchin's Colloquium of scholars. However, unexpected events prevent that from happening. Fifteen Ymisen galleons arrive in the harbor to force a trade agreement on Chynchin. Veycosi tries to help, hoping to prove himself with a bold move, but quickly finds himself in way over his head.

Bad turns to worse when malign forces start stirring. Pickens (children) are disappearing and an ancient invading army, long frozen into piche (tar) statues by island witches is stirring to life--led by the fearsome demon known as the Blackheart Man. Veycosi has problems in his polyamorous personal life, too. How much trouble can a poor student take? Or cause all by himself as the line between myth and history blends in this delightfully sly tale by one of greatest novelists.
