When a young man on the run from a criminal bounty flees to the neon-soaked streets of Chryse City, he becomes entangled with an immortal who keeps more secrets than friends. Dezi doesn't own the clothes on his back or the blood in his veins. He's a college dropout working a dead-end job on the most backwater planet humanity has ever colonized. He'd always dreamed of traveling the system, but when he's framed for a facility malfunction, he's forced to flee to the capital of Mars-a city teeming with gangs and space-age aristocracy. He manages to land a job at a luxury casino where a VIP selects him as his regular host. Umbra is a perennial, one of the few wealthy enough to extend their lives through a blood-based medical process, and he might be Dezi's ticket to paying off his bounty, but the immortal is as eccentric as he is generous. He claims to be an authentic vampire, and his appetites have Dezi questioning whether he might just be telling the truth. As Dezi falls headfirst into a web of seduction and deceit, he must decide what he's willing to do to survive a city where the weak end up as blood bags. For fans of Gideon the Ninth and Silver Under Nightfall, Bleeding Mars is a queer sci-fi that offers a fresh take on classic vampire tropes.
