Audrey is music-obsessed, quirky, charismatic, and so over Ethan. She dumps him, bored of his egotism and lack of personality. There's only one thing. Ethan's in a band. And when Audrey dumps him, he writes the song. "Audrey, Wait!" That song. The one that plays on every radio station. It's a hit with everybody, zooming to the top of the charts.
And it's about Audrey. Suddenly, she's a celebrity. There are people taking pictures of her at school, mobbing her at work, talking trash about her online... All she wants is to survive school, dance for hours at concerts, and maybe get to know her cute co-worker better. But can she have a life that even resembles normality when Ethan and The Song are out there?
I laughed until I couldn't breathe, couldn't wait to see what would happen to Audrey, Ethan, and everybody, and couldn't put the book down.
I'll be honest, the plot was slow at times. But it was a really interesting take on the whole suddenly-famous routine, and better done than most versions of the "I'm magically suddenly famous!" plot. And I adored the ending.
I love the characterization. The characters are introduced as real people, openly flawed, with real personalities. The interaction between the characters, too, is amazing, particularly Audrey's blooming ice-cream-shop romance with her co-worker.
My only complaint would be that Audrey slumps a little in the second half of the book, going a little angsty and boring for a few chapters. Luckily, she recovers and goes on to an amazing finish.
See above comment; I laughed and laughed and laughed. Showing/telling was balanced perfectly, description nicely done, characterization nearly exquisite. Let's just say I loved it.
End Result: five stars. A really excellent book. Read it.
