I have learned to dislike jumping into a series without reading the 1st book. But on this one, Demonglass gave enough info so I didn't have to go back to read the 1st one. Although I want to read the beginning, it was nice to get some of the additional info.
This book is worth the read, but I would suggest you read Hex Hall first ... otherwise when you jump back to read it, you will prob lose some of the interest ... LOL or something like that.
Now I have to hunt down Hex Hall (I hope the library has it). But off to read SpellBound, since I have it on hand :)
