Sarah Mlynowski has a very fresh voice and I'd read something by her again, despite that this one was just "okay" for me. There are realistic consequences in this YA, and things don't just magically resolve as is often the case in books targeted at this age group--YAY! I'd definitely recommend this one for older teens--adult readers may have a harder time with the premise (as I did), but will probably enjoy the humor. 
 (It's 99 cents for the Kindle at the moment, FYI.)
