Description

At the Penumbra, you might follow Juno Steel, a brooding, sharp-witted private eye on Mars, as he tangles with an elusive homme fatale, tracks dangerous artifacts of an ancient alien civilization, and faces his three greatest fears: heights, blood, and relationships. 

Or you might enter the world of the Second Citadel, where the merciless Sir Caroline must corral a team of emotionally distraught all-male knights to defend their city against mind-manipulating monsters...even the ones they’ve fallen in love with. 

Or you might tune into the not-too-distant future of Thirst, a future America somehow even worse than the present, where four couples must survive a dangerous reality TV competition designed by a sadistic host and a cheerfully violent Algorithm.

These audio dramas and more await you in the Penumbra, dear traveler. We hope you enjoy your stay. (Start with "1.01: Juno Steel and the Case of the Murderous Mask" to follow the Juno Steel series, "1.09: Second Citadel - The Head of the Janus Beast" to follow the Second Citadel series, or "THIRST S1E1: Icebreaker" to listen to the Thirst series. Or, listen from oldest to newest to hear everything as we released it.)
