: I found another source. An anthology published in 2004 includes a story by "Cassandra Claire." You can verify this by looking at the the last which I linked to Amazon as that Amazon record has a "Look Inside" for the book. Cassandra Claire is credited on the table of contents, in the story which runs from page 59 to 76, and the "About the authors" on page 290 which says "Cassandra Claire is a twenty-something writer living in New York City, where she has painted her apartment green. She has loved fantasy since her father introduced it to her when she was a child. This is her first published story." 

 Also, we don't have a WP:RS for "Cassie Claire" yet and so I'd propose adding "(Formerly Cassandra Claire)". |talk
