Hannah Alexander - Double Blind [Kindle azw3]

A virus is sweeping the Navajo reservation, and two of her childhood friends are dead. For Sheila Metcalf that's a call to leave Hideaway, Missouri, and return to Arizona. Neither her father's objections nor the arguments of Preston Black, the man who loves her, can stop Sheila from returning to the land of her youth. Her nursing skills are needed, and it's past time she found out the truth about her mother's long-ago death.

There's a medical mystery to unravel, secrets about the past to uncover and questions about the future to explore. Along the way, Sheila will need courage and strength--and faith that God will protect her and lead her to where she belongs.
