In "A Higher Loyalty: Truth, Lies, and Leadership", Comey will "explore what good, ethical leadership looks like and how it drives sound decisions", according to Pan Macmillan, which has acquired the publishing rights in the UK and the Commonwealth excluding Canada.
"Using examples from some of the highest-stakes situations in the past two decades of the American government, Comey will share yet-unheard anecdotes from his long and distinguished career," it said.
Jeremy Trevathan, Publisher at Pan Macmillan UK, said about the acquisition, "This is an extraordinary look at what leadership under pressure, in the highest of public offices, means from the point of view of someone who has experienced the best and the worst aspects of both.
"A Higher Loyalty" will be published in the UK on April 17, the same day Flatiron will publish the book in the US.

Comey served as director of the FBI from 2013 to 2017, appointed to the post by President Barack Obama.
He previously served as US Attorney for New York, and the United States Deputy Attorney General in the administration of President George W Bush.
Trump fired him on May 10, 2017, abruptly removing the top sleuth overseeing a criminal probe into whether the Trump campaign colluded with the Russian government to influence the 2016 presidential election that was won by the real estate mogul.
"You are hereby terminated and removed from the office, effective immediately," Trump said in a letter to Comey.
The move came days after Comey testified on Capitol Hill about the FBI's investigation into Russia's meddling into the US elections and a possible collusion between Trump campaign and Moscow.
