Marco and the Red Granny
by Mur Lafferty
Marco is a failed graphic artist and writer figuring he's at the end of his career when his ship comes in. The aliens that run the Moon (now nicknamed "Mollywood") want him and his work, and will pay well to get it. But when Marco meets an octogenarian lunar gladiator called The Red Granny, he learns there's a darker side to patronage, and he's not sure he wants in. But it may be too late.
