This book is "must have" for every Storyteller in - doesn't matter - old or new World of Darlness. 50 pages full of story ideas, new spells etc.
I played all World of Darkness settings and - believe me - "Glipmses of the Unknown" brings something new, some inspiration for every kind of it.
Without any needless blah blah from the very beging throws you into the new adventure.
What about price? It is real bargain if you consider how many hours (several hundrends I think) of fantastic gaming can provide.
Great job White Wolf!
