I’ve been reading the book Training for the New Alpinism, and it has a lot of info about how to train, and how to set goals for yourself to chase “whats next”. I have no idea your level of expertise - but given you just did Rainier I am going to assume you’re quite advanced. Congrats btw that’s awesome. If you’re interested specifically in Mt Blanc there’s another great book: Mont Blanc Massif - The 100 Finest Routes by Gaston Rébuffat. Paired together, both books would probably set you up very well for that mountain. https://www.amazon.com/Mont-Blanc-Massif-Finest-Routes/dp/0906371392 Good luck!
