Here we have books 1-4 of Magisterium, by Holly Black and Cassandra Clare. They are all first edition, first printing hardcovers with dust jackets, and are ex-library copies. There is writing on the top edge of each text block, indicating each book's number in the series. The first free end paper of each book also has writing on it, and there are library stamps on each book's title page.
