Hollow City is a great book! The Peculiars are wonderful characters (e.g. Horace becomes braver and Bronwyn is a fantastic mother figure to Olive and the others. ) and they all care deeply for each other. (Even Enoch has his moments.) There is some violence, but kids 10 and up should be able to handle it. The pictures are haunting and beautiful. Hollow City is a perfect mix of horror, adventure and romance. I love this book and I can't wait for the 3rd one. I hope you like Hollow City as much as I do.
