The People We Leave Behind [Spencer Reid]

Hazel Gilbert has spent her life searching for answers to a mystery that took place eighteen years before she was born. In 1963, her aunt Lainey, at just three years old, vanished without a trace. Since she was old enough to have memories, Hazel can recall watching her mother's spirit be plagued by this mystery. Hazel's mother, Joan, was in charge of her younger siblings that day. The year was now 2014, and the Gilbert family had been slapped with more devastating news. Joan had breast cancer. Her only dying wish was to find out what happened to Lainey. A 33 year old psychiatrist now, Hazel sought help from the one team she knew that could crack the case. The kidnapping occurred in a sleepy Indiana town. The kind of town where resources was scarce.

It had been a year since Maeve left Spencer. Spencer was still reeling from her loss. Some days it felt like he wasn't just living, just breathing to survive. That is until the day Hazel Gilbert stepped into the BAU headquarters with a mystery no profiler could resist. As Hazel and Spencer spend more time together, they become tangled deeper into the web of deception in this case. Spender also begins to notice familiar flutters in his heart. Was it really to late to solve the mystery of Lainey Briggs; or was the answer much closer than anyone expected?
