    I(?) have had great success at both
    grade levels with The Once and Future King (first book, Sword in the Stone--thanks
    Fran!) and The House on Mango Street. We dig all through Bob's Byway (the internet
    site) and keep our ears tuned to Cisneros' careful use of many of the literary
    devices found there, like metonymy and synecdoche, etc.  That leads to deep
    mandalas and good lit crit writing.  Another popular book at our school is A Tree
    Grows in Brooklyn, although I've never taught it.  My 10th graders get in with all
    their teeth to Night and A Separate Peace.
      One book that was interesting and produced good summer essays for 
    pre-honors reading was Kamala Markandaya's Nectar in a Sieve.
    Catalyst or Speak by Halse Anderson are great
    I have Tex, Farewell to Manzanar, Walkabout, The Acorn People as several of my
    novels for my general level sophs, in addition to Holes.  I have begun to do these
    using lit circles since meeting Harvey Daniels and reading his book.
    Definitely Tears of a Tiger by Sharon Draper.
    The first thing that popped into my head was Tears of the Tiger by Draper. I like
    the fact that the story is told through various voices.  It's short enough to not
    be daunting for less efficient readers, engaging enough to hook almost everybody,
    and challenging enough in its topic to give students something to chew on.  I
    could see lots of voice lessons, issues lessons, narrative flow lessons, writing
    invitations, etc., not to mention representation approaches working with this
    novel. I could even see web projects done in conjunction with this novel.
    The next thing that popped into my head was The Things They Carried by Obrien, but
    I suspect that is used in junior and senior classes???  But I love it's
    non-linear, collection of stories approach.  I probably didn't say that in a very
    english teachery way.  But I could also see lots of web project ideas
    here--connecting history to literature.  If there isn't enough technology access,
    then posters, brochures, mandalas (seems somebody wrote this book on mandalas.
    hmmmm)And, collages and essays about things kids carry, etc.  Oh the ideas....
    Last year, I used _Walk Two Moons_ by Sharon Creech in my remedial class.  I
    was initially concerned because I was afraid they would find the book too
    juvenile, but they really enjoyed it and responded well to it.  I also used
    _Burning Up_ by Caroline B. Cooney.  I really recommend taking a look at the
    first book, though.  In addition to being a fun read, it is an extremely
    well written story.
