In Cause to Kill, Homicide Detective Avery Black has been through hell. Once a top criminal defense attorney, she fell from grace when she managed to get a brilliant Harvard professor off - only to watch him kill again. She lost her husband and her daughter, and her life fell apart around her. Trying to redeem herself, Avery has turned to the other side of the law.

Working her way up the ranks, she has reached homicide detective, to the scorn of her fellow officers, who still remember what she did and who will always hate her. Yet even they cannot deny Avery’s brilliant mind, and when a disturbing serial killer strikes fear into the heart of Boston, killing girls from elite colleges, it is Avery to whom they turn. It is Avery’s chance to prove herself, to finally find the redemption she craves.

And yet, as she is soon to find out, Avery has come up against a killer as brilliant and daring as she.

In Cause to Run, a new serial killer is stalking Boston, killing his victims in bizarre ways, taunting the police with mysterious puzzles that reference the stars. As the stakes are upped and the pressure is on, the Boston Police Department is forced to call in its most brilliant - and most controversial - homicide detective: Avery Black. Avery, still reeling from her last case, finds herself up against a rival precinct and a brilliant, cunning killer who is always one step ahead of her. She is forced to enter his dark, twisted mind as he lays clues for his next killing.
