Shelf #2: Cassandra Clare
Normally I do not section my bookshelves off by authors but, like Rick Riordan, I seem to have acquired quite a few Cassandra Clare books and the collection only appears to be growing. I will admit that I have kind of fallen off of the bandwagon with her work—I have yet to read the final book in her Mortal Instruments series or the first in her The Dark Artifices series—but she still remains one of my favorite authors and I love looking at all of her books together on one shelf!
