Fred Brounian and his twin brother, George, were once co-CEOs of a New York City software company devoted to the creation of utopian virtual worlds. Now, in 2006, as two wars rage and the fifth anniversary of 9/11 approaches, George is in a coma, control of the company has been wrenched away by a military contracting conglomerate, and Fred is broke. Near despair, he's led by an attractive woman, Mira, to a neurological study promising "peak" experiences and a newfound spiritual outlook on life.

As the study progresses, lines between subject and experimenter blur, and reality becomes increasingly porous. Meanwhile, Fred finds himself caught up in what seems at first a cruel prank: a series of bizarre emails and texts that purport to be from his comatose brother.

Moving between the research hospitals of Manhattan, the streets of a meticulously planned Florida city, the neighborhoods of Brooklyn, and the uncanny, immersive worlds of urban disaster simulation; threading through military listserv geek-speak, Hindu cosmology, the maxims of outmoded self-help books, and the latest neuro-scientific breakthroughs, Luminarium is a brilliant exploration of the way we live now, a novel that's as much about the role technology and spirituality play in shaping our reality as it is about the undying bond between brothers, and the redemptive possibilities of love.
