The 57 Bus by Dashka Slater

Well documented.  I confess this is new territory for me with classifications of genders and pronouns, so I'm going to be neutral in writing this because of not sure which use of genders to use.
I am getting this book for my high school library.  It is excellent because of it shows both sides.  Builds a back story about all involved and Sasha recovers and Richard is forgiving.  Go on on this journey and read the story or listen to the audio book.
