Lauren Rivers was normal. Normal friends, normal mom, normal cats (okay, maybe her cat was a bit of a goof but she loved him very much). She did normal things with her sister. She nearly prided herself on normalcy. Her least normal aspect was that she had never known her father, but that was not "not normal," her mother would say. Everything changed when she met a girl and her brothers. The girl was Ava Riley, and her brothers were Damien, Kaleb, and Luca. As Lauren navigates her junior year with her best friend Charlie Willows, she discovers that the Riley siblings may be different than they seem at first glance. Will Lauren and Charlie get to the bottom of who the siblings are, or will unseen forces halt their investigations?
