Mary O'Sullivan makes her own rules now. Her first self-assigned mission? Track down the league retirees who killed her family, and enforce the long-overdue justice they deserve.

But Mary's crusade thrusts her deep into the shadows of vigilantism, where good and evil blur to gray. With her secret identity blown to shreds, she's beset by reporters and forced to seek unlikely allies.

When her enemies turn the tables and start hunting her, Mary must face the darker side of heroism—or risk becoming their next victim.

Follow Mary into the dark with the page-turning sequel to Alter Ego.
