Another segment in the world that is Infernal Devices! This novel moved along well and was full of new pieces of the puzzle to figure out how the characters in Infernal Devices relate to those in Mortal Instruments. The relationship between Will and Jem and Tessa took a surprising turn. Jem is so kind and good and sweet -- which was mentioned several times by various characters. Will had an epiphany, but it would be a spoiler if I told what it was. Will's family appears on the scene although he cannot contact them. Tessa is searching for what she is which she didn't totally discover -- fodder for the next book. Her brother rears his ugly head again and hurts more of the people he comes in contact with. There were few actual clockwork automatons in this one, but the ones that were featured were definitely beastly. Charlotte and Henry's managing of the Institute in London was questioned by Benedict Lightwood and they set out to prove their worth. Their relationship developed, nay came to a sweet realization, which I really loved.
