I found this book for free on Amazon, and the cover was funny so I downloaded it.
When I read it I found out that it is pretty consistently funny through out. I like Zuvela's humor, and he is a good artist. Most of the jokes made me laugh, or smile at least. I'm not quite sure who his style reminds me of, but it is well executed.
The humor is consistent, but it leans in different directions. Some of the jokes are working with the form itself like the last joke of the book where the joke hasn't been finished completely, other play with words like the one with a deer and a jar of honey in bed together, and yet another are fairly straight jokes.
In short, I like Zuvela's style, I find it funny, and may have to look up more of his work someday.
