Swan Knight's Sword

Gilberic Parzival Moth is a strange and lonely boy who has grown up without a father, raised by a single mother who moves from town to town in fear of something she will not name. His only friends are animals, with whom he has always been able to speak. And after surviving his bewildering encounter with the two kings of Elfland and their many strange and wonderful and terrible subjects, as chronicled in FEAST OF THE ELFS, Gilberic finds himself honor-bound to travel to a house of living death called the Green Chapel.
Accompanied only by his faithful dog and following the directions of a talking horse, Gilberic must go against his beloved mother's wishes and go in search of the Green Knight, the mysterious giant who is said to dwell in the chapel, and whom he had previously beheaded. SWAN KNIGHT'S SWORD is the third and final book of THE GREEN KNIGHT'S SQUIRE, the first volume of MOTH & COBWEB, an astonishing new series about magical worlds of Day, Night, and Twilight by John C. Wright.
