Dreadful Summer (Hayview Manor Series) by Jordan Elizabeth

Annie Carmichael is excited for the summer. Bonfires, the lake, and peaceful days on the family farm are just what she needs before her hectic, senior year begins. Best of all, her family hires a hot new farm hand who seems more than a little interested in her. The calm is shattered when her sister’s best friend, Nora, disappears, leaving behind her toddler son. The police are stumped, assuming the young woman simply left Cloverville. Annie’s sister knows Nora would never abandon her child. Annie sets out to discover the truth – one she may not want to really know.
