These are my guilty pleasure reading. I know book bloggers who secretly read the sappiest HEA harlequin romances who would never admit it in black and white. These are mine. There are a number of absolutely no-holds-barred series which are full of unapologetic punnery that make you moan and writhe in agony. They're more or less in the same genre. Of those series, including those by Glen Cook, Robert Asprin, Phil Foglio, Charles Stross, etc, these are my favorites. They're funny and full of awful puns and send-ups. They're mood lifters. (I work in a histology lab looking at cancer biopsies most every day - I read a lot of funny books to balance my work day).
Honestly the books go to the same place in my brain as MST3K and Sorority Babes in the Slimeball Bowl-o-Rama. If you're in the mood for complete silliness, they're just the thing.
The Dan Shamble books are all standalones. The author does refer back to things which happened earlier, but there aren't any deal-breaker spoilers. Mr. Anderson is a hugely prolific author, though much (most?) of his oeuvre is more serious fantasy/science fiction.
I heartily recommend these books as long as readers are fully aware they're very silly and full of groan-worthy puns and in-jokes.
Five stars. I'd give more if I could. They're goofy books. They're perfect.
