"Cadillac Beach" by Tim Dorsey narrated by George Wilson is a laugh riot for adults only. Well that's not exactly true, but the large amount of violence, sex, and drug use is not for young listeners. Eccentric Serge A. Storms is on a quest to find his grandfather's murderer and the stolen gems that were the reason for the death. Nothing will stop Serge, not the sanitarium, not the hired hitmen, not the sports reporter Serge kidnaps, and certainly not his plans to invade Cuba. Wild and crazy does not even begin to cover this whirlwind tour of Miami. Think of "Cadillac Beach" as a cross between Dave Barry and Hunter S. Thompson then kick it just shy of Thompson in the spectrum.
Janet Evanovich's Stephanie Plum series is excellent, but only when read by C.J. Critt. There has been a re-recording of the series narrated by Lorelei King and, frankly, she can't cut it. King's voice is dead and boring compared to Critt's energy and range of voices. Stephanie Plum is the newest bond enforcement agent in Trenton and is starting to make a name for herself as the Terror of Trenton. Start with "One For The Money" (the darkest of the series-the rest are lighter and much more fun) on the Recorded Books LLC versions. Critt also performs wonderfully on Evanovich's "Metro Girl" and "Motor Mouth."
Donald Westlake's Dortmunder series is another one that has translated to audio well. Westlake has developed the Dortmunder series into a genre all its own-the comedic crime caper. The series is read by Michael Cramer who has an incredible range of voices. "Drowned Hopes" is by far the magnus opus of the series, but the others should not be ignored. Look for "Why Me?", "Good Behavior", "Bad News" and "Don't Ask." The earlier novels "The Hot Rock", "Bankshot", and"Jimmy The Kid" show their age a bit, but are still fun reads (or in this case, listens).
