Many posts here at SF and Nonsense deal with science fiction. Some of the most viewed and commented-upon posts are about specific SF books. The odds are therefore good that you, Esteemed Visitor, are an SF reader.
I write SF for a living. Good friends do, too. Other good friends write in the evenings and on weekends, eagerly anticipating the day when they can also write full-time. All of which is to say, we and our colleagues produce the entertainment I have reason to believe that you enjoy.
In the upcoming season of gift-giving -- whether your observation of choice is Christmas or Festivus, Hanukkah or Kwanzaa, Bodhi Day or Boxing Day, Eid-al-Adha or Lohri, the winter solstice or the New Year ... or just holiday/post-holiday sales -- consider books. Print, e-, or audio ... they're all good.
Books aren't within your budget? Ask your library to acquire titles by your favorite authors. And let it be known what books you'd appreciate receiving as gifts.
My books? Genre books? Or any books? Your long-time favorite authors? Or experimenting with new authors? I (almost) don't care. I do care whether readers help to keep books (and publishing, and authoring) a going concern. Hopefully you want that, too.
And Happy Holidays!
