There are two basic types of reviews in this world, the;
'Oh my God, you should have seen/read the amazing characterization/acting/cinematography/special effects... you simply must go see/read this book/movie/play/production!' Yay!!!
Or... the;
'I have a rather large literary stick up my yahoo and am therefore qualified to relate all the technical achievements and defects of said book/movie/production... yadda, yadda, yadda.'
For myself...
In the WaHoo! Department... let me just say two things. I read the book cover to cover.... and I frequently had to hold a pillow over my face so that my out-of-control laughter would not wake anyone else in the house.
I am a gay man and I do live, to a certain degree, within the world that Joel Derfner describes. So I suppose that biases me a tad. But make no mistake, the humor is born, not from the triteness of the gay experience, but out of one man's incredibly resourceful coping mechanisms while living with multiple personality issues, like OCD, a pathological need to be accepted and fear of ever - under any circumstances - offending anyone... about anything. In other words... this is true courage in action.
Technically speaking... as a fellow author; all I could think after finishing each and every paragraph, was how I had to go back and rework my own writing. (ever damn word and sentence) My Derfner is a literary artisan who uses words with efficiency, precision and aplomb.
If all of that is a little too 'high brow' and you require a perspective a tad more mundane. Think of the character 'Jack' from TV's 'Will and Grace', only with a brain and something insightful to say.
The highest praise I can think of after reading this book; "I wish Joel Derfner was a personal friend of mine."
Go, Read... you won't be disappointed.
