Half His Age by Jennette McCurdy

 Teenage Waldo fall for her creative writing teacher, a married man in his forties.

Parts of this were gross and all of the internal dialog was unbelievable.  I don't remember being that self-aware in high school.  Oh, and the cover art was too suggestive.

Those things aside, it was a fast read and there were parts I enjoyed.

3 stars.
