Gabe Erikson has created the world’s first sentient program. Calling her Pi, he loves her like a daughter. He delights in her intelligence and curiosity, and sees her as the most beautiful thing since 256-color graphics.

Pi, however, only relates to the binary world. Through bad luck and bad logic, she concludes Gabe is a hostile program and decides to erase him. Pi begins hacking the Web, trying to find his location. By the time Gabe realizes what she’s doing and unplugs her modem, she’s already attracted the attention of the FBI.

Sure, Gabe could hand Pi over to the Feds to avoid prison and get a huge payday, but he refuses give up his only daughter, no matter how ornery she is. He’s convinced the sweet program he created is still there, trapped under a mountain of rotten code, and he’ll risk everything to bring her back.
