In an alternate version of the 1960s, two global superpowers have emerged after a savage war: the Zirnitra Union and the United Kingdom of Arnack. East and West are locked in a fierce race to send the first crewed flight into outer space, leading the Union to develop a secret agenda: the Nosferatu Project, which aims to use vampires as spaceflight test subjects. Similar to humans but feared and reviled, vampires are assumed to make the perfect “guinea pigs” for such a dangerous task. Lev Leps, a Union soldier and aspiring cosmonaut, is tasked with overseeing vampire Irina Luminesk aka N44, who has been chosen for the operation–and he can’t quite detach his feelings from the vampire girl as planned. Faced with pressure and peril, will either of them manage to fly into the cosmos?
