Romeo and What's Her Name — Shani Petroff

An unprepared understudy is forced to take the stage with her secret crush in this romantic YA comedy of errors from author Shani Petroff.

Understudies Never Get to Perform...
...which is why being Juliet's understudy in the school's yearly "Evening with Shakespeare" is the "perfect" role for Emily. She can earn some much-needed extra credit while pursuing her main goal of spending time with Wes, aka Romeo, aka the hottest, nicest guy in school (in her completely unbiased opinion). And she "meant" to learn her lines, really, it's just:

a) Shakespeare is HARD,
b) Amanda aka the "real" Juliet makes her run errands instead of lines, and
c) there's no point since Amanda would "never" miss he chance to be the star of the show.

Then, Amanda ends up in the hospital and Emily, as the (completely unprepared ) understudy, has to star in the most famous scene from William Shakespeare's "Romeo and Juliet" opposite the guy of her dreams. Oops?
