Coming Dawn

Konkoly’s uneven sequel to Deep Sleep picks up where its predecessor left off, with counterespionage expert Devin Gray in frantic pursuit of a Russian sleeper network in the U.S. that’s threatening cyber targets on both American and Ukrainian soil. In a Baltimore apartment complex, forces allied to the Russian oligarch Yuri Pichugin, who controls the recently exposed network, corner Gray and his fellow security operatives, intent on retrieving private records and access to national secrets that are now in Gray’s possession. After a long, bloody battle using the latest weaponry, Gray and his team beat back the attack and escape. Pichugin then uses cyberattacks to disrupt the defensive capability of Ukraine’s military in the face of Russia’s invasion. A fight with Gray’s forces later ensues on the top floors of a Miami, Fla., high-rise, the control center of Pichugin’s operation. Those who appreciate the adrenaline high of Konkoly’s blistering pace won’t be disappointed, but he spends little time explaining backstory, and even established fans would benefit from a glossary of technical terms and bro-tech slang. Tom Clancy it’s not. (Oct.)
