Ace Atkins is the author of the very popular Nick Travers series. Travers is an ex-New Orleans Saint who has become a part-time detective and is also a blues historian. The series is strongly weighted towards the blues music that Travers favors.
A second series features a returning army ranger who served in Afghanistan with the principal character named Quinn Colson.
As well as these two series Atkins has written 4 stand-alone books, the first of them, White Shadow, was a finalist for the 2007 Barry Award for Best Novel. These stand-alone novels are notable for the fact that they are based on real-life crimes that took place in the mid-20th century.
His most recent project has been to take up Robert B. Parker's Spenser series. The prolific author sadly and suddenly passed away in January 2010 at the age of 77 and the Spenser series to that point had reached an impressive 39 novels. For those of us who have enjoyed both Parker's Spenser series and Ace Atkins' work it will be a pleasure to read the continuation of the series.
