Fans of The Expanse will recognize the blend of systems-level conflict and human vulnerability though Gruger's book is more feral and less urbane; at moments it also feels like John Scalzi put on a darker less ironic face. This is for readers who want their science fiction to argue bruise and burn. Tyrants of Gravity is a sci-fi novel that thinks big and hits with surprising heart.</strong></p><p></p><p><strong style=background-color: rgba(255 255 255 1); color: rgba(15 17 17 1)>Feral sci-fi.&nbsp;Perfect for readers who enjoy the hard science fiction of James S. A. Corey and Andy Weir or Tom Clancy's techno-thrillers.</strong></p>
