Killer Within — Shannon Greenland

It's been three months since Lane made her first kill, and now she feels both closer and more alienated than ever from her united, grieving family. Haunted by conflicting memories of her mother, Lane resumes her role as the vigilante Masked Savior out of a feeling of obligation -- but her heart isn't in it anymore. Now that she's felt the rush of deeper, darker thrills, a growing part of her wants to revisit its seductive power, and she's not sure how long she can resist. Meanwhile, the Masked Savior has inspired its own fan site, and one of Lane's secret admirers is becoming a cunning copycat, exacting ''justice'' on defenseless innocents with increasing violence.
