Fresh from his cameo in "Sharknado 3! Oh Hell No!," "Game of Thrones" author George R.R. Martin will appear as a zombie version of himself in the second season of Syfy's "Z Nation."

We'll pause here for the inevitable chorus of "Just finish 'The Winds of Winter' already!"

Finished? OK. According to Entertainment Weekly, Martin will make a cameo in the eighth episode, where he's -- get this -- chained to a desk by the Collector, who captures celebrity zombies. Perhaps that's how he completed the novel a "Promise of Spring," a playful nod to "A Dream of Spring," the presumed title of the finale to "A Song of Ice and Fire."

"Z Nation" returns Friday at 10 p.m. ET/PT on Syfy.
