We are not alone, and it's our own damn fault....

Something demonic is stalking the brightest men and women in the computer industry. It attacks without warning or mercy, leaving its prey insane or comatose—or dead.

The mayhem is especially calamitous just now. Something far nastier than any virus, worm, or Trojan horse program is being evolved in laboratory confinement by well-intentioned but misguided researchers. When their artificial life-form escapes onto the Internet, no conventional defense against malicious software can begin to compete. As disasters multiply, computer scientist Doug Carey knows that unconventional measures may be civilization's last hope.

And that any artificial life-form learns very fast....

—Critical Mass

"Lerner's physics and computer science background serve him well for this pulse-pounding yarn about the creation of the first artificial life form inside cyberspace."
—BookPage Notable Title

"This is, in its truest sense, fiction about science. A tale in the great What if? tradition of many of science-fiction's most classic and well-remembered cautionary visions ... For those with an armchair interest in current science in all of its various disciplines, who can appreciate on a conceptual level the beauty of how science works, its implications, and how some of our most erstwhile writers take the fiction of science seriously, granting us their personal glimpses into the possible advantages and dangers from it in our ongoing exploration of the universe, then I recommend Edward M. Lerner's Fools' Experiments to you."

"A fun technothriller."
—Sacramento Book Review

"Contains one of the most meticulous descriptions of artificial life breeding experiments I ever read, and in understandable for non-programmers detail. It is almost on a par with Jules Verne's descriptions of ocean wonders seen from the Nautilus windows. That makes it definitely hard SF at the core.
