Alpine Ice has english in it. It's not as comprehensive as the Autour Mt. Blanc vol.2 book, but you can use it to help work out approach, descent, etc for routes it doesn't feature, and it's not too hard to work out the gist of the descriptions in the french guide - especially if you spend a bit of time with Google Translate.
As I recall a nice-looking local guide was recently published, but I don't remember seeing an english version
