In reply to UKC Gear:
Thank you for such a positive review. You've hit the nail on the head I think.
It was always aimed at first timers and families with a holiday plan which includes a few mountain sports. For those with higher and harder ambitions the excellent Patrick Col guides (in French) will undoubtedly earn a place on your bookshelf. These are widely available in the valley and are mentioned in my guide book.
We'll be in the valley in the summer for a few weeks and hope to see some fellow Brits enjoying these beautiful mountains by whatever means take their fancy.
A bientot!
