A grieving doctor fights back against the world's growing inhumanity...

"Rubin's revenge thriller is fast-paced and full of plenty of unexpected twists and turns...a true page-turner"—Kirkus Reviews

To her Boston patients, Dr. Hope Sullivan is a conscientious doctor with a caring bedside manner. To her victims, she is a fierce protector of those who have been wronged. After losing everyone close to her, these revenge "tune-ups" are the only thing that make her feel...well...feel anything at all.

Until one day, a mysterious email threatens to expose her. I know what ur doing, it says.

At first, Hope ignores the electronic stalking, but when the threats become increasingly personal, she knows she must act. It isn't until the stalker gives Hope a taste of her own medicine that she uncovers a far greater danger, both to herself and to the patients she cares for.
