I LOVE JAMES HERONDALE! I've only read this, the Midnight Heir and a few excerpts about Jamie and I just know I'll absolutely adore him by the time Chain of Thorns comes out! 
 Matthew Fairchild. Need I say more? He is so much like a Herondale, I feel like he and James were switched at birth or something. I though Matthew would be the quiet one and James would be like Will and Jace, but I guess James is more like Tessa. 
 At the end I aww-ing when James said he did want to be Matthew's parabatai. It was so cute! I absolutely can't wait for more Jatthew/Mames!
