Pretty weak stuff, sad to say. It starts with a bang with the first story, and had me very much excited--but the rest of the work isn't nearly of as high a quality. The other standouts are the Lee and Tuttle stories:
The Tanith Lee story is basically just The Fog but retold in Lee's great prose, so that's a plus.
The Tuttle story is classic Tuttle--dark explorations of family emotional dynamics with a genre overlay--and good, but I'd just read it in a standalone Tuttle collection so its inclusion here didn't rate as highly for me as maybe it should have.
Otherwise, the stories are mostly competent but uninteresting, or else overly confusing (and not in a good way).
If you have Kindle Unlimited or see it at the library, then it might be worth checking out on the basis of the stories I mentioned (and, horror being subjective, you may find others you like as well). but it's just sort of...meh.
