Catching Up

Two Years Overdue left off with Erin on a long return home. With no car, little money, and no phone, all this story needs now is "it's up to Jay to find her." But is it he who does? Meantime, what's going on with the rest of the squad as they try to locate the gang responsible for Jay and Erin leaving in the first place? Involves Chicago Fire characters. I do not own Chicago P.D.
