I Thought You Didn't Care

What would you do if, one day, your best friend just told you "I don't care about you anymore, never really have, and I never will ever again" ? Well that's what happened to Aria Morgen when her best- erm.. ex-best friend, Logan Welch, told her those exact words after school on their first day of high school. Now, the only thing Aria wants to do is find out why he said those things after nine years of friendship. Will Aria find out why? Will she find something else along the way? Or will their friendship be lost forever?
