Coming soonish from Subterranean Press - the first collection of my short fiction in about a decade - here's the cover (by @alisonsampson.bsky.social ) and table of contents for your delectation.

Book cover showing the glass bubble of a space helmet with a woman's face and hand reflected in it, and ants crawling over it.

Returned proofs of Loss Protocol to my publisher on Friday; sent the MS of Heaven’s Grand Design to my agent today. Might take the rest of the week off.
