Dr. Beckett by Zoe Rose

A brilliant doctor. A tenacious nurse practitioner.
A perfect match… A hunt for answers.
Dr. Zach Beckett is the best in his field, but his social skills leave a lot to be desired.
Nurses can’t keep their eyes off him. Everyone wants to be with him.
But when a young patient of his dies under mysterious circumstances, he’ll need more than good looks to find answers.
Nurse Practitioner Kelly Monk isn’t interested in reliving the past, but six years after breaking Zach’s heart, her life has come full circle.
Unfortunately, the up-and-coming virologist has more than just troubles of the heart to confront.
When Zach recruits her to search for answers about his dead patient, they discover similar cases of teenagers dying under a yet unknown illness.
Help from a pair of doctors gives them hope… until they’re both found dead.
The creators of this mysterious disease are desperate enough to prevent anyone from digging into the cases.
Does this strange case have a connection to other similar ones around the country?
