Philip K. Dick meets Neal Stephenson in a tale of programmable reality

When an unconventional offshoot of the US military trains an artificial intelligence in the dark arts that humanity calls “black magic,” it learns how to hack the fabric of reality itself. It can teleport matter. It can confer immunity to bullets. And it decides that obscure Silicon Valley middle manager Adrian Ross is the primary threat to its existence.

Soon Adrian is on the run, wanted by every authority, with no idea how or why he could be a threat. His predicament seems hopeless; his future, nonexistent. But when he investigates the AI and its creators, he discovers his problems are even stranger than they seem…and unearths revelations that will propel him on a journey — and a love story — across worlds, eras, and minds.

Previous Novels

Travel Thrillers and Vertigo Crime

Jon’s critically acclaimed “travel technothrillers” — Dark Places, Blood Price, Invisible Armies, Night of Knives, and Swarm — are an interlinked series of novels depicting the 2000s era of globalization, the rise of the Internet and smartphones, and their collective impact on the developing world … as seen through the eyes of travelers caught up in extraordinary (and extraordinarily dangerous) situations across far-flung corners of the world: Nepal, Indonesia, Morocco, the war-torn Balkans, coastal Belize, kaleidoscopic India, Uganda, Zimbabwe, Colombia, Haiti, Dubai, and beyond. They were published by HarperCollins in North America, and Hodder & Stoughton in the UK/worldwide. Dark Places won the Arthur Ellis Award for Best First Novel.

His Vertigo Crime graphic novel The Executor, one of Comic Book Resources’ Top Ten of 2010, is a dark tale set in a small border region caught — stuck, really — between the US and Canada, good and evil, the haunted past and the unimaginable future.

Beasts of New York

Jon’s previous and — until now — most beloved novel is a dark and epic fantasy about the squirrels of Central Park. Published in a gorgeous print edition by The Porcupine’s Quill, it is now free to read online.
