By that I mean a book that you think you are going to fall so desperately in love with, or else that is going to change you so deeply, or even that you are scared to dislike, that you cannot get on with it? If so, why?

For my part, I've been sitting on Always Coming Home by Ursula K. Le Guin for months. She's my absolute favourite author and ever since I was, I think, eleven and a poor writer I've wanted to make a fictional anthropological textbook. God, even just inventories of people's lives, without the need for an overarching plot. Having this book in my shelves is taunting and wistful and wonderful all at the same time, and I'm scared I'm going to love it so much that I will become a mad acolyte.
