This book is really great at teaching you what will happen in the end time while still keeping you entertained. The charactors are very real and you feel like you know them at a personal level.The authors are able to use suspence to keep you wanting to read the next book. It just kinda gets confusing with all the different stories going on though.I would definatly recommend this book to anyone.
