This book collects Matheson's vampire novella I Am Legend with 10 of his short stories (also horror of various types, though vampires don't make an appearance in them). I read I Am Legend by itself earlier this year, and gave it 4 stars. The shorts don't quite stack up to that, I'm afraid. With the exception of one of them, "Mad House" (which was creepy and excellent if a wee bit dodgy in its science) they were fairly unremarkable - and some were downright obvious. On their own, I'd probably have given them 2 stars, so averaging it out the collection earns a 3.

Honestly, you're probably better off just reading the novella.
