Cassandra Clare, Sarah Rees Brennan, Maureen Johnson and Robin Wasserman come together to make a minor character become a central figure in the Shadowhunter legacy.
Simon Lewis, nerd, geek, recently undead, decides he will become Nephilim.  Of course that means self-examination, sacrifice and no pizza. Pretty difficult for a boy from New York.
A variety of guest instructors tell their history which fleshes out the history of Simon.  Very well written with thought provoking moments that will make the reader analyze their motives in life. 
Excellent read!!!!!
