Hi, I have been asked to find/suggest a font for a book cover.
My client has asked for a font which reflects "Firmness, originality, truthfulness, honesty, integrity, etc.
Frankly, I have no idea what he is asking for so could use some help.
Any ideas?

I'd keep it simple, as nothing will satisfy someone who comes up with these qualities for a font. How about Helvetica Neue?
Clean, nice, legible, honest, firm

Probably less original and I know nothing of the truth...
