Fans of the GLASS AND STEELE and THE GLASS LIBRARY series will delight in the new magical historical mystery by USA Today and Wall Street Journal bestselling author, C.J. Archer. Set in the years between the two series, the first volume of Professor Gavin Nash’s memoir features beloved characters on a quest for a rare book.

When Gavin travels to Edinburgh with his good friend Oscar Barratt, he’s eager to acquire a centuries-old book on witchcraft for the soon-to-open Glass Library. Even with ruthless railroad magnate John J. Defoe in the bidding, the victory comes easily. Perhaps too easily.

Hours later, the book is stolen.

A single clue links the theft to the recent abduction of two women, both magicians. Desperate to recover the book, Gavin and Oscar find an unexpected ally in Defoe’s enigmatic assistant, Miss Wheeler. But as they delve into the mystery, they uncover far more than they bargained a secretive sect, a descendant of the Witchfinder General, and forbidden love letters.

With time running out for the kidnapped women, can the unlikely trio untangle the lies from the truth before the magicians—and the book—are lost forever?

Enjoyable read for Glass and Steele fans

This is a fairly short story compared with the Glass and Steele books, and takes place following those books end but before the Glass Library books. It follows the adventures of Oscar Barrett and Professor Nash as they collect books on magic for the Glass Library… and apparently have Sherlock Holmes-style adventures solving mysteries along the way.
We even get to see a glimpse of Willie’s married life.

Off to a Good Start

Nice to find many old friends from previous Glass book series briefly seen. There were previous references to Professor Nash’s travels so enjoyed reading this first one. Also interesting to watch him blossom into a skilled detective while being teased by his companion. See another book promised and hope there will be more as the author further develops the two lead characters and sends them on new challenges.

A cozy read spanning the two worlds of Glass and Steele and the Glass Library. I doubt there will be a ton of book spanning intrigues in this series like there are in the other two since it’s a prequel of sorts to the Glass Library, but it’s enjoyable nonetheless for the quirky personality of Professor Nash as the narrator and another chance to enjoy this world built by CJ Archer with appearances by some of our favorite characters!

I loved loved LOVED this for so many reasons. The nostalgic feeling of revisiting the Glass and Steele characters, the insight into the early lives of some of the characters of the Glass Library and of course the story. CJ Archer, you are a true story magician yourself! Roll on September for the next book

Its so much fun to read of Professor Nash and his adventure with Oscar. I can't wait to read the next one. I've read all of the companion series Glass and Steele,and the Glass Library. Definitely go back to read these gems. CJ Archer is an excellent historical writer.

Laws of Witchcraft

Another winner from C.J. Archer. Her books with the intrigue and such excellent characters are always winners. This book started a little slow but definitely picked up in pace. It was enjoyable to read something that occurred during the other books that she wrote.

Archer picked two good secondary characters to lead this new series. I like that this takes magic outside of England and shows how the Glass Library acquires some of its books. I also enjoyed the cameos from the original (and future) characters for her other two series.

*Audiobook. I was expecting more witchy magic. Instead it’s more of a cosy mystery novel. The narration was very well done.

Two of CJ Archer’s worlds combine in this one with the World of Glass and Steele softening slightly into the cozy mystery world of Cleo Fox.

Oscar and Gavin are great parallels to Sherlock and Watson in this story. It’s true CJ Archer formula, where each book will have its own individual mystery to solve but will have overarching plot lines that you’ll enjoy exploring as you read.

Quick read as well so perfect for a weekend!
