I must say in advance that I am a very big fan of Cassandra Clare and her books. The City of Bones series I really like, but "The Infernal Devices" is even better for me. The time and place are exactly my taste. =)
Clockwork Princess is a great sequel. They seamlessly extended CP and stands when it comes to humor, romance and Co. The other two books in every way. Tessa, Will and Jem accompany the reader and give plenty of reasons to laugh, cry, hope and fear!
At the end I will say nothing to no desire to take on reading! =)
For those who have doubts about whether they can understand the book in English well here's a tip. Lest best before the other two books in English, so that you special words you read in advance. Otherwise, you can read the book very well and understand.
Enjoy reading and for all girls -> Imagine willing ne tempobox! : D
PS: Unfortunately, I can forgive only 5 star here! = /
