There is some ambiguity about where Shot of Tequila fits into the Jack Daniels series.
Technically, it is the first book in the series, because it takes place before Jack becomes a Lieutenant. But it really isn't Jack's book. She's a supporting character, not the main one. The main character is a mobster named Tequila.
Tequila later appears in Serial Killers Uncut, Spree, and Last Call.
I purposely write each of my books so it can be read without any prior knowledge of any of the others. If you want to start on the last book and work backwards, or start in the middle, you can still enjoy the series without missing anything.
That said, some readers do want a chronological list of events in Jack's life. So here it is.
Besides the eight Jack Daniels novels, Jack and her cohorts have appeared as supporting characters in several other books and stories. Here's the order, from her years as a rookie cop, to the future.
