Great book for middle schoolers
After reading ttyl and ttfn, I have a very different impression, and find your summary misleading. Even though the topics you mention come up, they come up within a context of three girls who are close friends and are trying to figure out how to deal with some of the very real and complicated situations of their lives. When one of the three considers participating in questionable behavior, her friends do not support those bad choices, nor do they remain silent. They are there to encourage her to make better choices. Instead of encouraging dangerous actions, they openly point out factors the one is not considering, and model how to be true friends. Their conversations express realistic topics students in middle school grapple with, and when one of them might start to make bad choices, in this YA novel, there are bad consequences that follow. These characters live within today's world, and yet remain supportive and concerned for each other. Poor choices are not romanticized or glorified. I highly recommend it for all middle school readers.
