Sarah of Forever Young Adult gives a great summery (and fab review) of THIS SONG WILL SAVE YOUR LIFE by Leila Sales:
"To say that Elise Dembowski is unpopular would be an understatement. In the world of Mean Girls, she wouldn't even sit at Janis and Damien's table. If this was The Breakfast Club, she'd be Ally Sheedy without the eventual makeover. Even Rachel Leigh Cook had a friend in She's All That, which is one more than Elise has, unless you count her dad. (And obviously, including parents on your friend list is the number one sign that you're not cool.)
Cursed with the dreaded "weird" label, Elise has basically become invisible, except for the occasional moments when a popular kid needs an emotional punching bag. No matter what she does, she can't seem to fit in, and eventually, she comes to the conclusion that the only option is suicide. Fortunately for Elise (and all of us), she botches the attempt to end her life. But it's not until months later that she actually begins to feel alive again, thanks to her discovery of Start, an underground dance party in an abandoned warehouse. With help from the resident DJ, Char, Elise unleashes her musical passion on the turntables as her heart experiences the new beat of happiness. Soon, she's a high school loser by day and the city's hottest DJ by night, but even Elise doesn't have the skills to keep her two worlds in sync, and it's only a matter of time before they collide in a climactic cacophony."
