One of the hundred books a year I read:

Detective Nap Dumas remains haunted by tragic events during the senior year of high school. His girlfriend disappeared under a flimsy excuse that she was transferring to a private school and no longer wanted contact. At that vanishing act happened at the same time Nap’s twin brother and his brother’s girlfriend committed suicide by jumping in front of a train.

In the next state, a city police officer is gunned down in what appears to be a routine traffic stop. Dumas is first shocked to discover the officer was a former high school classmate. But, worse, Dumas’ old high school girlfriend’s fingerprints are found on the scene.

As Dumas pokes at the crime, he discovers more. His brother and others were members of a secret society in high school, intent on uncovering the real use of a federal government facility near their school. As Dumas attempts to track down other members of the secret society, he discovers more suicides and disappearances.

Are all the deaths and disappearances connected? Did a secret at the government facility get them killed? Or is the crime something much worse?
