The Cedar Key by Stephenia H. McGee

Could the key to Casey’s future be hidden in someone else’s past?

Casey Adams unexpectedly inherits an old Victorian house full of other people’s memories. Stuck in a quirky little Mississippi town, Casey’s hope for a fresh start died as soon she had to lay the grandmother she’d just met to rest.
But Grandma Ida carried secrets beyond the grave.
Before her death Ida carefully planned a trail of clues to help Casey unlock the Macintyre family secrets and finally explain why they abandoned her. But each of Ida’s letters will only come from Casey’s handsome—and often frustrating—new neighbor. As Casey pieces together the stories behind the objects filling her grandmother’s house, she embarks on a heart-stirring journey that rattles her foundations, ignites her faith, and leads her to a startling discovery that will reshape her future. But only if she can face the lies that have been slowly tearing her apart.
