A very special Gryphon Chronicles story, for all those who love A Christmas Carol and savor the joys and traditions of a Victorian Christmas. Humbug hates being a Christmas elf. Instead of making toys, he'd rather make mischief. Angling for a new job in Halloween Town, he sets out to prove he's frightful enough for the post by ruining Christmas for as many people as possible - until Jake and his friends manage to capture the little troublemaker, determined to put a stop to his devious schemes. When the kids find out that Santa is offering a reward of 'One Christmas Wish Granted' for the safe return of his runaway elf, the gang sets out on a rip-roaring, snowbound adventure to the North Pole to hand Humbug over and collect the bounty. But the way is fraught with danger, leaving Jake and his pals to wonder if they'll make it home in time for Christmas - or if they'll even make it back alive! (236 pages / 51,801 words)
