Subject: Re: Torino, Piemonte, Asti, Alba, etc.
Hi Callie, maybe it is not what you are looking for, but the Lonely Planet series has a book for Milan, Turin and Genoa. It has sections on the Aosta Valley and the Lakes.

The Rough Guides might have something. I have seen their Italy guide and it is quite good.
