Colton 911 by Beth Cornelison

Two friends track a lethal murderer as a childhood bond is put on the line.

Disgraced FBI agent Nolan Colton returns home to lick his wounds…only to find death on his doorstep. After a woman’s body is dug up in a parking lot, his longtime friend PI Summer Davies enlists his crime-solving expertise. Nolan can’t help but admire all-grown-up Summer’s tenacity, but new leads take their case in a killer direction — one that threatens the future of their entire case…and their own lives.
