The Book of Boy | Catherine Gilbert Murdock

The year is 1350. Boy, a hunchbacked, sweet-natured goatherd, is content in his quiet country life. But when a shadowy pilgrim with a dangerous past arrives on the farm, his world is turned upside down. Secundus is a man on a mission, and upon first sight of Boy, enlists him as his servant, ripping him away from tranquillity and plunging them both into a perilous medieval treasure hunt ... but there is more to the pilgrim's quest than meets the eye.
