My published works shall be on display and perhaps some fan goodies

Biostration is where art and science synergize. Gary Raham writes science fact and science fiction and often illustrates his own work. Visitors will be able to purchase books, prints, and original paintings that will explore the creative interface of art and science. He will feature the 2018 Colorado Authors’ League Award Finalist SF novel, A Once-Dead Genius in the Kennel of Master Morticue Ambergrand. Kirkus Reviews said, “The arch tone should remind readers of Kurt Vonnegut, although Raham is better grounded in exobiology and science and displays a more upbeat outlook for the human (and non-human) condition in this engaging tale.”
