The only light left burning
(Book)

"After a long and treacherous journey south, Andrew and Jamie have finally found safety in the Florida Keys. But they soon learn that safety doesn't always mean happily ever after. Settling into life in the Islamorada colony with other survivors of the bug, Andrew believes they've finally found themselves a home, even a family. But anxious Jamie is less comfortable in their new community and is eager to return north to keep the promise they made to their friend Henri—to bring her to the colony and reunite her with her daughter. Besides, would it really be so bad to find someplace just for the two of them? When a hurricane and a shocking betrayal force them to leave the colony in search of new shelter, it brings their tensions to a head—and puts them in the path of some old enemies. Andrew and Jamie must set aside their differences to survive once more and find a new home. But what if 'home' means different things to each of them?" --publisher's website
