Those trained to save lives might be the most skilled at taking them.

Paramedic Anneliese Ashmore’s routine shift takes a startling turn when she answers the call she was never meant to hear—a call to a crime scene where her sister, Sydney, is the victim of an overdose suicide.

The evidence says otherwise.

In the midst of a heated divorce, motive implicates Sydney’s soon-to-be ex-husband. While the police focus on the single lead, Ana makes her own discovery.

A chain of e-mails between Sydney and her surgeon’s office sets Ana on a search for answers about her sister’s recent diagnosis and the life-altering treatment that saved her. The body count rises as Ana closes in on the truth and on the man of her dreams.

With the help of Dr. Jared Monroe, an unhappily married physician with a bit of a crush, Ana uncovers a ring of greed and corruption and exposes the fact that Sydney’s medical treatment may have been the catalyst for her murder.

Unfortunately for Ana, she may be next.
