Well so far I have read two of the Shadows anthology books edited by Charles L. Grant and I must say they were both quite good. Grant has selected excellent stories and some are quite spooky indeed, there isn't a dud in the lot.
While some of the other anthologies only have a few strong stories (the mammoth book of horror series for example) Grant has chosen to keep out the filler resulting is a far better anthology, just got in volume 4 last week and going to work my way right through to the end. Something tells me I won't be disappointed.
