This book was quite boring. Mirrodin was pretty slow too but this one was just hard to finish even though is was about 300 pages long. One problem I noticed from the time I picked up the book was that it was a different author from who wrote Mirrodin. I mean come on! HOw can you make a succesful block with 3 different authors(Fifth DAwn has a different author as well).
Also theres not enough characters, you get tired of just reading about Glissa, Bosh, Slobad, and the wolf(forgot his name) running away from nim and Vedalken. And they are constantly fighting and running away all through the book. It gets kind of old after awhile. I don't really even feel like finishing up the series.
If you hadn't start reading the series yet dont! Read the Onslauhgt block and legends block instead.
