Loved it!It was very interesting to read through IMs, and see all of the characters' lives unfolding. The characters are very likable, though. Frankly, Maddie is too rebellious and does a lot of stupid stuff, Zoe is too judgmental, aloof and straight-laced. The only one I like is Angela. Though boy crazy and obsessed with clothes and make up, she actually does care about her friends and tries her best to be good person.
