This is a good series. But to get the full picture of this first book you will first need to read The Silver Series where it all began. Currently books 4 & 5 are not available for purchase ( there 7 books ), which is disappointing to say the least. But all in all it is a good read.
A good 'teens read. I read a lot of YA novels but found this just that bit too young for me. Nonetheless a good tale that's imaginative and refreshing, even though I didn't finish it due to the maturity level.
