I draw comics about the books I read.
I love this! I agree that there's usually no going back -- if for some inexplicable reason a book didn't hold my attention the first time, it almost never does the second time either.
Currently trying to read 'Adrian Mole The Prostate Years' again after giving up previously. It is too depressing - it doesn't even try to be funny like the originals. I will finish it, but only once I have drugged myself up with some Hitchhikers Guide to the Galaxy first.
