Black Sun by Owen Matthews is a gripping thriller that held my attention from the first page. Set in 1961 in the ultra-secret Soviet city of Arzamas-16, the story is set against a high-stakes project to build the world’s most powerful nuclear bomb. A young physicist dies under suspicious circumstances and KGB Major Alexander Vasin is sent to investigate, only to discover an elite city of scientists working in secret.

Black Sun is very well paced. The author crafts an easy-to-follow plot that pulled me along at just the right speed, building anticipation with each chapter. The plot alone made the book hard to put down and despite the inevitable Physics of nuclear bomb construction was never overwhelming or confusing. The characters are also impressively constructed. The author gives them just enough backstory to make them feel real and relatable without slowing the story. I found myself invested in each character’s motivations, which added an emotional depth to the story that’s rare in thrillers.

The book is based on a real event and the story, setting and characters feel authentic, capturing the atmosphere of paranoia and ambition that defined that era and culture.

Matthews has created a compelling, thoughtful novel, easily as good as and possibly better than Tom Rob Smith’s USSR-era books such as Agent 6. I thoroughly enjoyed reading Owen Matthews’ Black Sun and am excited to know that it is the first in a three-book series.
