“Brennan’s most ambitious novel to date is an engaging adventure thriller showing how just a few changed moments in history—perhaps even chosen by the reader themselves—can alter our world forever. The spine-chilling descriptions will remain with me long after finishing it.” — Francis French, author, In the Shadow of the Moon “Gerald Brennan’s new Cold War thriller is a bracing, surreal look at what could have happened juxtaposed with the shock of the new, all set against the background of a proposed crewed reconnaissance program in low Earth orbit. You won’t be able to put it down!” — Emily Carney, blogger and space historian, AmericaSpace ""Though 'alternate' and 'alternative' history are often used interchangeably, the words don’t mean the same thing. The fourth installment of Gerald Brennan’s Altered Space series is shaped by a sustained engagement with the very concept of alternatives: wrenching decisions and random occurrences that determine the course of stories, histories, and individual lives. Employing the scrupulous detail of classic technothrillers alongside James-Ellroy-esque reality-scrambling and a fractal elegance that recalls the work of Agustín Fernández Mallo, Infinite Blues plays out against the perilous backdrop of a reimagined Cold War in which the conquest of space has been undertaken neither in peace nor for all mankind."" — Martin Seay, author, The Mirror Thief ""Tense, dense and claustrophobic, Infinite Blues is a captivating Cold War thriller from a world that never was—hitting the ground running like an alt-history Hunt for Red October in space, and escalating the paranoia as it boils to its inexorable conclusion(s)."" — David Hitt, author, Homesteading Space
