Pretty little wife
(Book)

"Lila Ridgefield lives in an idyllic college town, but not everything is what it seems. Lila isn't what she seems. A student vanished months ago. Now, Lila's husband, Aaron, is also missing. At first these cases are treated as horrible coincidences until it's discovered the student is really the third of three unexplained disappearances over the last few years. The police are desperate to find the connection, if there even is one. Little do they know they might be stumbling over only part of the truth. With the small town in an uproar, everyone is worried about the whereabouts of their beloved high school teacher. Everyone except Lila, his wife. She's definitely confused about her missing husband but only because she was the last person to see his body, and now it's gone" --Publisher.
