Book Cover

I was thinking of calling my question book '?', but it looks like the title can't be just punctuation, so I was thinking 'The Rocco Effect - ?'

What do you think of the name?

What do you think of the cover?

Is my blurb good, or would you like more info?

I'm still unsure I can't see what's wrong, maybe new eyes will be able to help.

Thanks

Rocco
