Almost everything by Adrian Tchaikovsky, specifically the trilogies Children of Time, Dogs of War, Final Architecture; stand alone novels Shroud, Cage of Souls and Alien Clay and the novellas Ogres, Elder Race and Saturation Point. The man is prolific af and his concepts are absolutely original, sometimes mind-blowing, always thought-provoking. Since we’re dating 2012 The Expanse is top tier, bar none and their new series The Captives War is awesome as well.
