BOOK BLURB
It’s been four decades since the women of Sigma Delta Tau were last together. The passing years, growing families, and maturing careers may have strained the bonds of sisterhood, but now a reunion at the Western ranch of one member offers an opportunity to renew acquaintances…and at least one long-standing grudge.
Still, this weekend is supposed to be a pleasant diversion for former sorority member and current private investigator Aubrey Merritt. She’s come to New Mexico to reconnect with old friends and she’s brought along her personal assistant, Olivia Blunt—an aspiring detective who is learning more about packing bags on this trip than about solving crimes.
The shocking murder of a sorority sister changes everything. With the local police overmatched, all eyes turn to Merritt and Blunt to crack the case. With a surprising abundance of suspects, it’s going to take both of them to cut through the knot of old hurts and current grievances to find the killer.

MY REVIEW
The Forty-Year Grudge is the second book in the Merritt & Blunt Mysteries series. Aubrey Merritt is a private investigator. Olivia Blunt is her assistant and aspiring detective. While The Forty-Year Grudge can be read as a standalone novel, I recommend starting with the first book, The World’s Greatest Detective and Her Just Okay Assistant.
In The Forty-Year Grudge, Merritt travels to New Mexico and reconnects with her former sorority sisters. Blunt comes along on the trip to help. When one of the sorority sisters is murdered, Merritt and Blunt work to solve the case.
This is a cozy mystery with dry humor. Interesting characters and a fun mystery.
I received a digital copy of this book from the publisher via NetGalley in exchange for an honest review.
