A mysterious installation somewhere in the cosmos serves as a ramshackle way station for a colorful variety of humans gone missing throughout the multiverse in Frechette’s SF novel.

Somewhere in space, the Crossroads is a wheel-shaped habitat built by the “founders” (possibly aliens) and kept running by aging robots and a somewhat inconsistent crew of humans. It hosts new arrivals from the masses of Homo sapiensthroughout the multiverse who, over centuries, have simply disappeared—via wormholes, black holes, freak teleports, or accidents (cave-ins, plane crashes) leaving no traces of survivors. Most of these “Transients” are shunted to fresh existences elsewhere; depending on their behavior and how much they can pay, Transients can find a pleasant landing somewhere else in the universe or be dropped into slavery (or worse). Other Transients become long-term residents (“Barnacles”) or functionaries of the Crossroads. Beth McDee is a streetwise, unhoused Black lesbian from 1980s South Florida who arrives via a plane mishap and learns she has natural skills that might allow her to advance in the Crossroads hierarchy—if she follows the rules. Renata is an academic from the early 1970s obsessed with the Bermuda Triangle who deliberately arrived at the Crossroads in a tiny boat. Flavius commands of a quartet of Roman soldiers and is tasked with instituting the Crossroads’ first human police force; Sakhmat is a long-term staffer, an oft-fiery ancient Egyptian noblewoman whose Sapphic leanings lead to an ill-starred affair with Beth. Beth and Renata get to tell their stories first-person, in semi-hip dialogue (“not my first ride at this rodeo”). The characters’ interlinked comings, goings, and evolutions twine with the mounting crisis of the Crossroads showing its decrepitude. By the ending (which teases the possibility of a sequel), the full truth about the place remains undisclosed—Frechette’s emphasis throughout the story is more on characterization and relationships than mind-blowing science or hefty technology. This convivial yarn might appeal to fans of Spider Robinson’s fondly remembered Callahan’s Crosstime Saloonseries, but it nicely finds its own way.

An enjoyable, seriocomic space yarn about the ultimate grand central station.
