"Imperium is the most expensive structure ever created. Once an orbiting laboratory, it is now a space hotel for the fantastically wealthy. But as the station preps for its first group of space tourists, Dr. Chloe Bonilla, Imperium's resident biophysicist, finds herself questioning whether babysitting a passel of space glampers is worth the distraction from her research. A private rocket delivers a rogues' gallery of the world's elite to Imperium: eccentric billionaires, callow tech bros, a sponsored Instagram influencer, and a seemingly saintly philanthropist. However, posing among the staff are members of a global terrorist group who call themselves the Reckoners, hell bent on upending the economic inequality of twenty-first-century Earth--and they have a bone to pick with these scions of the 1 percent. As the Reckoners take control of Imperium and demand an $8 billion ransom from their wealthy hostages, it's up to Dr. Bonilla to save them, and fast. Or the captives will be forced to exit the station--and there's only one way out."--Provided by publisher.
