Twenty-nine-year-old Lisa Newberry can barely make it through the day. Suddenly widowed and a survivor of a near-fatal attack, she is wracked with grief and despair. Then she hears of a medical trial for a tiny brain chip that emits electrical pulses to heal severe depression. At rope's end, Lisa offers herself as a candidate.
When she receives her letter of acceptance for the trial, Lisa is at first hopeful. But-brain surgery. Can she really go through with that? What if she receives only the placebo? What if something far worse goes wrong?
