Alrighty, since this is a December book and it right smack in the middle of several holidays that revolve around family, giving, celebrating, we are giving you your options.
Now, keep in mind that the book you vote for can have holidays included, but that it will heavily have to be dependent and expressive towards that subject.
If you vote BoJoy, then your story is about joy, in any context. It doesn't have to have anything to do with any holiday going on right now.
If you vote BoGifting, this will have to be about giving and receiving gifts, though not necessarily concentrating on the holidays that have that as a theme.
If you vote BoFamily, then your story is heavily about family. It doesn't have to have anything to do with holidays at all, though it can. But Family is the primary subject.
If you vote BoCelebrations, then this is almost exclusively this season's celebrations. To list a few, there is Christmas, Hanukkah, Kwanzaa, New Year's.
