I just started reading Rolling Thunder by A. J. Devlin. This book is the second in the "Hammerhead" Jed Mystery series and will be released May 15, 2020.
As a former professional wrestler and new private investigator with one murder case behind him, Jed "Hammerhead" Ounstead has seen a lot. But nothing could have prepared him for the world of women's flat-track roller derby. An old wrestling acquaintance has entered the roller derby scene and calls on Jed when her team's coach goes missing. Jed will have to keep his wits and his wrestling moves sharp as he navigates the various venues of Vancouver in search of the missing man.
