How do i get my mom to let me read Eclipse?

I'm 12 (going on 13 in 2 months) and I read Twilight & New Moon in four days (during meals, cl, 'till four in the morning, on the bus, in the car, at dinner in a restaurant.) My mother scolded me for reading those 2 books for those whole four days and i only got 12 hours of sleep total for four days and now it has been 2 months and I'm starving for Eclipse. I have to, have to read it or i feel i will fail to exist, BUT my mother says there is to much "a huggin' and a kissin'" I have been asking about every day for a week if i could read it and she keeps saying ask later so i do the next day and she says maybe and i don't know and maybe again. I need to break this ongoing block of maybe's and IDK's but i don't know how. I have considered reading it behind her back but i know that i would surely expose myself for once a book is in my hands it's stuck there until its over. I almost never use bookmarks now! So I'm trying to use the read-it-behind-her-back as a last resort. I need other ideas on what to say and what to do to get her to let me read the book. I waited 2 months for eclipse and i think i can wait longer for breaking dawn because from what i have heard I'm definitely not gonna be allowed to read it till I'm 15 or 18. Anyway, i just need to know what to say and do so i can soon be stuck in eclipse.
