This book collects a coven's worth of very good stories, but just to be different I'll offer a quote from the About the Author biography page: "If genres were wall-building nations, Lucy's stories would be forging passports, jumping fences, swimming rivers and dodging bullets." Yep, that pretty well nails it. Spinwebs in particular can be taken a number of ways, as well as Dura Mater, an epistolary sf/horror tale. Jessie Shimmer Goes to Hell is, obviously, an entry in the Spellbent universe, though I doubt anyone who wasn't already familiar with the background would get much from it. Approaching Lavender is a poignant body-snatcher piece. Two of the stories were written in collaboration with Gary A. Braunbeck; the very short The Still-Life Drama of Passing Cars, a sort of Twilight Zone piece, and Fable Fusion, a Dr. Who story (#7, with Ace) which is quite good and is a sharp counterpoint in tone, theme, and style to the rest of the stories in the book. Through Thy Bounty, a very early story which also appeared in her earlier collection Sparks and Shadows, is a nice homage to Damon Knight and answers the question: Okay, it's a cookbook, now what do we do? My favorite stories are the Lovecraftian Cthylla and The Abomination of Fensmere and two stories with deep influence from Robert W. Chambers, The Girl With the Star-Stained Soul, and While the Black Stars Burn, from which the collection gets its title. I thought it was very neat that The Abomination of Fensmere leads directly into The Girl With the Star-Stained Soul; they're quite different stories, but it's the same story.
For anyone who can't afford to vacation in Carcosa this year, this book is the next best thing.
