I ripped through this 570+ page book as fast as I could, and apart from the last 100 pages or so, thought it was pretty terrific. Witches and vampires, intrigue about missing manuscripts, and a knock-out love story -- what could be bad about that? The plot moves along at a swift clip, with twists and turns galore, yet I did think that ultimately the story didn't quite hang together as well I might have liked. The last quarter of the book felt a little too crammed, with too many new character, in a somewhat forced situation. This is the first book in what I've heard will be a trilogy, and it seemed to me that the author was trying a bit too hard at the end to lay the foundation for what comes next, rather than wrapping up this volume in a more satisfying way. I do recommend "A Discovery of Witches" to anyone who likes a good supernatural story. I just wish I'd liked the last 100 pages as much as all the rest.
