NEW NOVEL OUT OCTOBER 27: THE POPE'S HITMAN
Publisher’s Weekly: "[A] riveting action thriller [for] fans of Frederick Forsyth’s conspiracy novels…"
The Optionist: "[R]idiculously over-the-top and I loved every second of it."
John Wick meets Conclave in this fast-paced international thriller about a priest with a deadly secret who must stop a plot to kill the Pope on Christmas Eve.
Everybody loves Father Francis Loyola, the humble pastor of a Catholic church in Boston. But his world is turned upside down when a sniper attack during Sunday Mass forces him to confront his long-buried past as a covert assassin in service to the Pope.
To uncover the truth about who is behind the attack, Loyola must take on old enemies and former allies, all while evading the dogged investigation of homicide detective Martina Rocha and interference from enigmatic nun Sister Belina Fortis.
Loyola’s search for answers will take him from the streets of Boston to a fortified compound in Bosnia, a medieval castle in France, and finally Rome, pursued every step of the way by an army of fanatic monks, armed American mercenaries, and Interpol investigators.
An exhilarating and cinematic novel filled with nonstop action, The Pope’s Hitman will be a hit with readers of Lee Child and Dan Brown.

A rising tide of extremist movements threatens to destabilize civil societies around the globe. It has never been more important to understand extremism, yet scholars and policy makers can't even define who is an extremist and why. In this volume in the MIT Press Essential Knowledge series, J. M. Berger offers an introduction to extremist movements, explaining what extremism is, how extremist ideologies are constructed, and why extremism can escalate into violence. Available in six languages, including English, Arabic, Spanish, Chinese, Korean, and Finnish.

"Optimal is a brilliant exploration of the implications of ceding our personal responsibility and relying on algorithms to teach us how to live. But more than that, it’s great storytelling." -- Hahvi.net
"I was hooked from the first chapter - not because it's so deep, but in spite of that. ... In other words, it's fun to read. You barely notice how terrifying the implications are until you're too far in to care..." -- Amazon Vine Voice reviewer
"Jessica Stern and J.M. Berger's new book, 'ISIS,' should be required reading for every politician and policymaker... Their smart, granular analysis is a bracing antidote to both facile dismissals and wild exaggerations... a nuanced and readable account of the ideological and organizational origins of the group." -- Washington Post
The definitive book on Americans who joined jihadist movements from the 1970s through 2011.
"Berger lifts the veil on the phenomenon of American jihadists in this timely and chilling examination." -- Publisher's Weekly
"A sober, factual account of the Americans who have been lured to the cause of religious violence, offers a useful reminder that this phenomenon is nothing new, long predating the Sept. 11 attacks." -- New York Times
