Joanne makes her home the perfect place for Christmas so her grandchildren will always remember the holiday. She even puts her Christmas cards on the banister.

But this year, she faces a dilemma. Her father has been in a coma since Thanksgiving, but a Christmas card from him arrived in mid-December. Even stranger, the letter inside gets longer every time she looks at it.

Her father always made up fantasy worlds, but now Joanne feels like she's living inside one—and she wants to leave.

"Kristine Kathryn Rusch's eerie and slow-starting 'The Last Christmas Letter' decisively delivers the Twilight Zone's trademark out-of-this-world wonder...exceptional, with vivid characters and some mind-bending narrative moments."
