Art, like literature, can open up new worlds. Unfortunately we can't reach into a Cezanne and try a piece of fruit or ask the Mona Lisa why she's smiling, but in the world of City of Bones, it's possible for a work of art to hide tangible secrets that you can pull out of it. Plus, City of Bones not only features a main character who aspires to be an artist and whose mother is an artist, but it also features a lot of references to famous artists, both classical and modern.
