A criminologist out for justice.
A BAU agent desperate to save his career.
A dangerous path that can make them whole...or leave them in pieces.

FBI criminologist January Reese is on the hunt. A homicide victim robbed of one of her organs fits the motive behind two previous serial cases, and she senses a connection.

As January and Lincoln unravel a puzzle of greed and desperation, they must rediscover the trust...
