I've been searching for a website that basically does something very similar to the following flow chart (link if it's too small to see):

I'm basically looking for a site that asks simple questions like the flowchart does and gives a single book recommendation.
I found www.whatshouldireadnext.com but that basically gives a list of recommendations based off of Amazon's "Costomers who bought this also bought..." database (I'm assuming)
Does anyone know of anything like this? Am I SOL?
