Booklist, starred review

“Exciting, action-packed and absolutely marvelous.

Kirkus, starred review

“Moriarty has once again fashioned a complex mystery and adventure that is as twisted and unexpected as the stairways and rooms of the tenement buildings he so adeptly describes.”

School Library Journal 

Spin State

“A hefty far-future exploration of AI, human cloning, class conflict and plain old-fashioned murder … Beneath this complex tale ominously simmers Orwell’s question: If all animals are to be equal, what can prevent some from making themselves more equal than the others?”

Publishers Weekly

“Action, mystery and drama, set against some of the most plausible speculative physics I’ve seen.”

—David Brin

Winner of the 2006 Philip K. Dick Award

“[T]his richly textured second novel explores issues of identity and loyalty, swapping quantum mechanics for complexity theory and mystery for suspense … Arkady, an entomologist assigned to a terraforming project … comes into possession of two pieces of information: one very valuable, the other very damaging … Through Arkady’s bewildered eyes, the reader discovers a future world where America is a rogue nation and the most precious commodities are water and the ability to bear children.”

Ghost Spin

Complexity is the watchword here, of thought, idea, narrative, character and plot … Highly rewarding, but you’ll need to bring along plenty of active brain cells.


“In Moriarty’s high-stakes, tension-riddled addition to visions of the posthuman future, the characters have the complexity of motivation and backstory to make this more than just another dire-future thriller.”
