The thing about Janet Evanovich's Stephanie Plum series is that they're an incredibly fast read and they're highly entertaining. After 13 novels, they are formulaic but so what? I admire the author who can take the same formula and have it equal a slightly different result each time. 
 I enjoyed Lean Mean Thirteen. Stephanie had a lot to deal with: her ex-husband, Dickie Orr disappears, presumably murdered, and she's the prime suspect. Of course, she goes digging into Dickie's life and come across a possible mob connected money laundering conspiracy. Not to mention her day to day dealings with various FTAs, her family, and her loves, Det. Joe Morelli and Ranger. 
 I enjoyed the case and the conspiracy mystery of LMT. It was a pretty smart one. I liked the FTAs especially the taxidermist because he wasn't a bad guy; just a victim of Big Bad Cable. I really liked that The Burg felt more like a place I can visit and thank the universe I don't live there. 
 What I have liked for awhile in each Stephanie Plum mystery is that each book is a little more realistic, considerably. The wackiness of her family has been a bit muted. I enjoy it more. Also, Evanovich has had Stephanie grow up and become a bit aware of the bounty hunter world she's gotten herself into. Stephanie is not the same girl from One From the Money and that's a good thing.
