Loved this book!
First off, if you haven't read the "Darkness" series, you might want to give it a read. "City in Embers" loosely ties with the events in Brown's first series--the electrical storm caused by Ember and the rumor of fae power transfer mentioned by the Seelie Queen. Reading "Darkness" will give you a foundation, but, it isn't required to read those books. "City in Embers" does an excellent job on its own.
Brown created another strong, confident female protagonist in Zoey Daniels. You can't help but like her. She's had a tough life but will stand up and fight for what she believes in. And, Ryker, a burly fae, is her strong counterpart. Their storyline was well-developed. By the end of the book, you want to read more about them and their odd relationship.
Once again, Brown works her magic with descriptions. The devastation after the ES was so visual. I had no problem picturing the characters in this book.
"City in Embers" continues giving readers a background in Irish folklore. The stone mentioned in the book is legendary. It is obvious Brown does considerable research when crafting her stories.
The only thing I disliked about the book? I finished it in two days! It is a page turner which delivers a serious cliffhanger. I hope Book Two is on its way to the publisher!
