What if you woke up one morning, and everything changed?
It´s one week before Christmas Eve, and Haruhi and the S.O.S. Brigade (a club for her high school´s strangest and most extraordinary students) are gearing up for holiday festivities. But just before the fun kicks off, Kyon, the only ´normal´ member, wakes up in a weird alternate dimension, one where Haruhi attends another school entirely, Nagato the time travelling robot is just an ordinary human, and Mikuru (the cute girl of Kyon´s dreams) doesn´t even recognize him - in other words, S.O.S. Brigade never existed.
The only clue Kyon can find is a bookmark left by the robot version of Nagato, which leads him on a quest back in time, where he interacts with the storyline from ´Bamboo Leaf Rhapsody´, a short story from the previous Haruhi book, The Boredom of Haruhi Suzumiya.
This fun and quirky holiday tale is reminiscent of A Christmas Carol and It´s a Wonderful Life.
