MixedScience\"Impey does an admirable job describing multiple facets of the often contradictory field of black hole astrophysics, including its history, science, and colorful human interactions ... Anyone who has read and enjoyed Kip Thorne\'s gold standard, Black Holes and Time Warps, will learn relatively little from Einstein\'s Monsters ... For the next generation of popular astronomy buffs, Einstein\'s Monsters is a reasonable entry point, covering a broad—if not particularly deep—range of theoretical and observational topics in black hole research. Particularly welcome, even for more experienced black hole aficionados, are the excellent chapters about the Laser Interferometer Gravitational-Wave Observatory\'s recent discovery of gravitational waves and the Event Horizon Telescope\'s imminent discovery of black hole shadows ... Unfortunately, this prolific productivity is occasionally betrayed by factual errors in the text, especially in the more theoretical passages ... Certain passages, and even chapters, of Einstein\'s Monsters have a distinctly hap-hazard feel to them, throwing together a collection of topics without an obvious theme ...
Despite these few shortcomings, Einstein\'s Monsters will be sure to capture the imagination of most who pick it up, simultaneously convincing the reader that these monsters, while in fact quite certainly real, should be loved and not feared.\
