When victims of a serial killer are found dead by injection of a new pharmaceutical, Morgan Stark, a brilliant doctor turned FBI agent, is summoned. With an abundance of theories as to the motive and murder, Morgan may be the only one who can wade through the medical possibilities to enter this killer’s mind. But will he be too late?

Too Far Gone is book 3 in a new series by number one best-selling and critically acclaimed mystery and suspense author Rylie Dark, which begins with Too Late (book 1).

Morgan Stark is a renowned surgeon, acclaimed by his colleagues for his brilliance as a diagnostician. But when his close friend and protégé resident is murdered, Morgan feels compelled to help the FBI decipher the trail of medical clues and bring the killer to justice.

FBI Special Agent Danielle Hernandez, 28, a rising star in the BAU, equally esteemed by her colleagues for her brilliance and determination, is not used to turning to a doctor for help in solving crimes. This unlikely partnership, though, may just surprise them both.

Morgan and Danielle grapple with the motive behind this erratic killer. Why use a drug that saves people to kill them? Might the killer himself be sick? Could rival pharmaceutical companies be involved?

But Morgan and Danielle feel the motive is more primal.
And that this killer, if not stopped, will soon strike again.

A cat-and-mouse thriller with harrowing twists and turns and filled with heart-pounding suspense, the Morgan Stark mystery series offers a fresh twist on the genre as it introduces two brilliant protagonists who will make you fall in love and keep you listening late into the night.

Books 4 and 5 in the series—Too Lost and Too Broken—are now also available.
