Lizzy Ballard possesses a dangerous power she struggles to control: the ability to inflict fatal brain injuries using only the power of her mind. Haunted by the memory of her victims, she's on the run from the authorities and from the scientist who created her power, Louise Mortensen.

Lizzy has been hiding out in Arizona with her mentor, ex-con Philip Castillo. She's earning money at the poker tables of Phoenix, thanks to an unexpected ability bestowed by a drug stolen from Mortensen: temporary clairvoyance. When Lizzy and Philip decide to head east to Lizzy's hometown of Philadelphia, she's overjoyed to be reunited with her godfather, Owen McNally, and his brother Andy.

But the East Coast proves to be no refuge when Lizzy is the subject of a brutal attack. Then Mortensen kidnaps Andy and coerces Philip into a lethal game of nerves with her rival, Billy Chapel. Lizzy sees no way out except to comply with the demands of her nemesis.

When Lizzy finds blood stains in Chapel's suite and a dire note from Philip warning her of who the true enemy is, she fears the worse. She demands answers from Chapel, but he's just as baffled as she is. His confusion quickly turns to rage, and he drags her toward Louise's lab?and the final showdown.

Outnumbered but undaunted, Lizzy must rely on her wits and grit to try to outmaneuver Mortensen and Chapel, and to answer the question: can friendship and justice prevail against cruelty and evil?

The only way to win might be to put not just her freedom but her very soul at stake.
