Lifelines by CJ Lyons is the first in a series that takes place at Pittsburgh's Angels of Mercy Medical Center. Lydia is the new ER attending physician, Amanda is a med student, Gina is a resident, and Nora is a no-nonsense charge nurse. Lifelines is really Lydia's story more than the other women's, but you do get to see glimpses of each woman life so you learn a little bit about each.
Lifelines opens up with a patient dying in the ER and Lydia being put on probation. There is no apparent reason for the death and it becomes even more troubling after several more unrelated deaths occur on Lydia's watch. With both mystery and romance, Lyons keeps the reader glued to the book until the very end. I had never read anything by CJ Lyons before, but will make sure to find her books in the future.
