I recently read, was astounded by, reviewed and am stymied why Seven and a half tons of steel by Janet Nolan didn't get more attention!
I also agree with YA Book Nerd that Barbara Dee's Truth or Dare should've received more love. It's a book that every girl needs to read.
I also wish that Monika Schröder got more attention. Her books are quietly lovely and Be Light Like a Bird was so poignant.
