Endpapers is a great story for those interested in the concepts of identity and oppression in New York in the early 2000's. I enjoyed the mystery of a secret love letter, the historical references to 9/11 and Nazi Germany, and the discussions of gender and sexuality. If you want a more mature (and better written) version of Felix Ever After this is the book to read! It dragged out a little towards the end but the main story kept me engaged and I was empathetic with all the characters.
