The fracking boom in eastern Montana has minted a handful of new millionaires and one billionaire: Lee Rossman, the president of Rossman Mining and the leading philanthropist in the small city of Rawlings. Rossman is the last person Detectives Seagate and Miner expect to discover dead in the alley next to a strip club. Later, when Lee's son is found out at the rigs, with significant internal injuries, numerous broken bones, and a belly full of fracking liquid, the detectives know the two crimes are related but can't figure out how. In their toughest case yet, Seagate and Miner try to solve a mystery awash in enormous fortunes, thwarted ambitions, and grudges both old and new.
