"...an excellent protrayal of how nanotechnology may one day penetrate human society..." –Tom Easton, Analog

"...Nagata's theme is both ambitious and important: the attempted political regulation of new technologies, especially as they relate to human rights..." –Gary K. Wolfe, Locus

For Katie Kishida, the nanotechnology revolution begins with an act of love. Katie is a young mother with a successful career and a loving marriage, when her perfect life is shattered by the sudden death of her husband, Tom. Putting her faith in a science that hasn't been invented yet, Katie has Tom's body placed in cryonic suspension—frozen in liquid nitrogen against a time when advances in nanotechnology might heal his injuries and restore his life. Katie never suspects the consequences that will follow. Tom's death and his costly entombment spark immediate political controversy. It's a debate that only grows more passionate as the years pass. Katie's life is taken over by the need to defend her husband's future and to shepherd into existence the controversial technologies that might let him live again . . . even as she's haunted by the question: Does Tom really want to come back?

Tech-Heaven is a compelling story of devotion and unyielding determination set amid the tumultuous politics of our time, in a world that is teetering on the cusp of a technological revolution like no other in history.
