How to Read the Ghost-in-Law Mysteries Series
The Ghost-in-Law Mysteries series, written by New York Times bestselling author Jana DeLeon, is a delightful blend of cozy mystery, paranormal romance, and laugh-out-loud Southern comedy. The series is set in the fictional, humid bayou town of Mudbug, Louisiana, where the local rumor mill runs fast, and the gators aren't the only things lurking in the swamps. At the heart of the series is Helena Henry, a manipulative, overbearing, and downright sassy mother-in-law who refuses to let a little thing like death stop her from meddling in the lives of the living. After being murdered, Helena returns as a ghost to haunt her daughter-in-law and orchestrate the investigation into her own demise.
For the best experience, the series should be read in publication order. Because each book builds upon the relationships, running jokes, and the overarching mystery of who Helena was (and who killed her), reading them out of sequence can spoil key plot points. Below is the complete reading path, including the core novels and the companion novellas that flesh out this hilarious supernatural universe.
Ghost-in-Law Books in Recommended Reading Order
1. Trouble in Mudbug (2009)
The series kicks off with the book that started it all. Scientist Maryse Robicheaux thinks her troubles are finally over when her controlling and manipulative mother-in-law, Helena Henry, dies.

2. The Helena Diaries (2013) — Companion Novella
Though published later, this companion novella is a direct diary compilation written from Helena Henry’s perspective during the events of Trouble in Mudbug.

The case pushes Colt and Jadyn's professional and personal relationship to the limit.
8. Rose and Helena Save Christmas (2014) — Crossover Novella
This festive holiday novella is a unique crossover co-authored by Jana DeLeon and Denise Grover Swank.

They must team up with Taylor and the meddlesome ghost Helena to clear their names and find the real killer before Christmas is ruined.
What to Know Before You Start
The Ghost-in-Law Mysteries are designed to be fun, breezy, and highly entertaining reads. While the romantic pairings shift across the books—following Maryse and Luc, Sabine and her PI, Raissa and Zach, and finally Jadyn and Colt—Helena Henry remains the constant thread that binds the Mudbug community together. Readers looking for high-accuracy scientific or procedural investigations might find the small-town antics exaggerated, but fans of Janet Evanovich's Stephanie Plum series will feel right at home with the comedic suspense and quirky side characters. The books successfully deliver a warm, swamp-grown charm that makes the fictional town of Mudbug a place you will want to visit again and serialise in order.
