The Truth According to Us by Annie Barrows
Miss Layla Black despises small-town life.
After refusing to marry the man her rich father has picked for her, Layla is banished to the remote town of Macedonia, West Virginia, a place where nothing important ever happens - or so she thinks.
Tasked to write down the history of the town, Layla meets the seductive Romeyn clan. As she peels back the layers of family feuds and deceit, she discovers to her cost an unknown story far darker than she could ever have imagined.
