I am currently reading my way through a long list of science fiction and fantasy titles. (http://www.npr.org/2011/08/07/138938145/science-fiction-and-fantasy-finalists if you are interested in the list).
I gave this book a break and switched to Sherlock Holmes. Returning to The Ginger Man, I found it much easier to see what Donleavy is doing--I get the satire now.
Just proves that you DO have to be in the right frame of mind for certain novels.
Now, I must push to the finish, as it's due at the library SOON.
