A murder story with a devilish twist

Nick wants a cell phone so he can talk to his girlfriend, Jen, after school, but he doesn't have a lot of money. The used phone he buys seems like a bargain, until the phone calls begin--strangers calling night and day, some begging for help, others making demands. Nick wants to get rid of the phone, but something prevents him, and, soon he finds himself committing crimes--stealing, conning . . .and killing.

Fans of William Sleator's The Boy Who Couldn't Die will enjoy this equally diabolical thriller.
