They are the Tannenbaum Tailors: elves charged with maintaining Christmas trees in homes around the world. Without the Tailors' efforts, families might lose their Christmas spirit. And this year, one team of Tailors will be tested like never before. With the North Pole itself under attack, newly promoted Captain Brendan is assigned a special mission: conceal the source of Santa's power within a Christmas tree in Chicago. On Christmas Eve, Santa will pick it up. The job would be simple, but the Tailors find themselves facing a serious threat-the thieving Spiritless elves, already responsible for sabotaging the North Pole Home Tree, will do anything to gain control of the very thing that makes Christmas possible. Equally bad, Christmas spirit is at an all-time low in the Chicago home where Brendan's assigned. The family's mother even wants to take the tree down before Christmas Eve! To save Christmas, Captain Brendan and his Tailors will have to use every spirit-raising trick they know-and possibly even bend a few rules to pull it off. Combining holiday cheer with action and thrills, The Tannenbaum Tailors and the Secret Snowball reads like Raiders of the Lost Ark in a Christmas tree.
