The Teninson Files - The Fifth Brother

This is the third installment in a series that follows the life and times of super sleuth Jeffrey Teninson.
The first book followed Jeffrey through two marriages, during which he fathered three children: Andrew, with his first wife, Lynn Parton; and Rylan and Ayla, from his second wife, the former Luna Tibs. Each child has a unique set of skills inherited from the complex DNA they received from their father. Jeffrey also has a daughter, Julie, adopted from his first wife’s relationship with another man. Julie is older than the other children and is in the process of establishing law offices in Woodward and Oklahoma City. The four children and the two wives remain actively involved in the Teninson household, creating a complex environment.
The second in the series, ＂The Family,＂ continues the saga with a missing person’s case that becomes increasingly bizarre as it uncovers an unbelievable trove of hidden secrets. Jeffrey Teninson meets three half-brothers and finally understands what the FBI has been doing to him his whole life. Additionally, he is forced to confront his mother, a witch who has survived for hundreds of years by taking over the bodies of her female offspring as she ages. Amid all the chaos, Jeffrey discovers he has another half-brother who had evaded capture in a case Jeffrey solved years earlier.
The third book in the series, ＂The Fifth Brother,＂ follows Jeffrey Teninson as he tries to find his older brother. The question is, ＂Why is he so determined to find someone who appears to have no interest in being found?＂
