Gravity of Sol-3 (Paperback) (ISBN-13: 9798990032712)

The Sentinels have been watching Earth for a century.

The Sentinels are here to suppress Earth's technological advancements and an emerging human neurodivergence that would violate galactic laws.

Ostracized by a human society poisoned by the Sentinels' propaganda, physicist Scott Anderson breaks the Sentinels' rules. In 2055, Scott captures primordial black holes, which are the size of protons but have the mass of mountains and a million megatons of potential energy. These tiny black holes could power human interstellar travel and planet-killing weaponry-the same physics advancement the Sentinels prohibit. Scott is torn between scientific ambitions and protecting his nine-year-old autistic brother, Robby, who carries a rare genetic trait outlawed by the Sentinels.

The Sentinels are here to subjugate the human race and destroy the defiant. Scott dares to combat the aliens using the power of primordial black holes.
