Rekindled Light (Coastal Lights Legacy #4)
Marilyn Turk

Lieutenant Josiah Hamilton has returned to Pensacola as well, as an engineer for the US Army with orders to find the original lens of the Pensacola Lighthouse and build the new keepers’ house. He still loves Sarah, but when he sees her with a young child, assumes she is married, and the child is hers. Meanwhile, Josiah is being pursued by the lightkeeper’s daughter and distracted by an apparent plot to prevent him from carrying out his job.
Who is the arsonist starting fires at area lumber mills? What will happen when Sarah’s life and Josiah’s mission collide with someone who wants to end them both?
