Kendra Cavelli is a 26 year old Homicide Detective for the Aurora Police Department. Her life is complicated; losing her former retired partner and dealing with a new family. Kendra's father, Sean, recently discovered he was accidentally switched at birth and is truly a Cavanaugh and now part of an affluent and huge family. Used to the senior partner, the spirited Kendra is a loner until learning of her new partner, the sinfully good looking and extremely tall Matthew Abilene. Still coping with the death of her fiancée she is extremely bitter at his suicide.

Partnering together is the beginning of bickering and adjustments as Kendra is tagged with the nickname "Good" and gives back as good as she gets. Matthew is known to have a following of women of his choice and has no intention of beginning a permanent relationship with anyone. Investigating a murder and following the twisted clues, things get a little steamed between them and neither is able to pull back. Not only is the case sizzling but the sex is hot as a firecracker leaving both wanting more. The humorous taunting aside Matthew soon proves to be a competent partner and things are turning serious between them. Once Matthew realizes this is not a one night stand, finding a way to convince the feisty female to give in to her feelings is an all-consuming project for him.

Another story of the Cavanaugh family and their family of policemen centers this time on the daughter, Kendra. Giving up on love and feeling outcast and guilty over the suicide, Kendra wards off commitment. The humorous bickering and bantering keeps CAVANAUGH RULE alive and fun to read. CAVANAUGH RULE is another chapter in the family saga which I very much enjoyed. I look forward to more from Marie Ferrarella about this very interesting family.
