Taking a delightful departure from his more common urban-fantasy settings, this epic tale from acclaimed author Charles de Lint weaves elements of Celtic and Nordic mythology while bringing sword and sorcery to the forefront. Summer magic is waning in the Green Isles, and the evil Icelord is encasing the lands in a permanent frost while coastal towns are pillaged by snake ships. Mounting one last defense against the onslaught, a mysterious old wizard instructs his inexperienced apprentice in the art of shape-changing. Mercilessly pursued by the Icelord's army, this newfound mage gathers allies—a seemingly ordinary young woman and her protective adoptive family—and they flee north in a desperate race to awaken the Summerlord. Time is running short for the Summerborn, especially when a treacherous family betrayal is discovered.
