"The Ruby Dice", by Catherine Asaro. This week we open the Grimoire Cage and unleash that most dangerous of bibliographic bogeymen: the Choose-Your-Own-Adventure book! Your stalwart hosts recount very different experiences on their voyage through the number-coded pages of a vast and sprawling adventure, with naught but their wits — such as they are — and a studious commitment to sincere literary reportage to guide them. K battles a Space Dragon (who may or may not be a pirate). Khaki invents a collective noun for Velibraraptors. Find CoverMyAssCast on Twitter, Gmail and www.covermyasscast.com.
