Anyone who performed or vended at either "Big Faire", which is what Californians call the two nine week long every summer Rennaisance Faires, one Northern, one Southern, will recognize this book as a fantasy utilizing what happened when Southern Faire's site for years was bulldozed and the Faire had to move. Not surprising as Lackey herself has connections to the Faire folk.
Other than that, the book itself is interesting, not the least because it broke Lackey's invariable pattern of doing trilogies. Knight of Ghosts and Shadows is actually the second book in a "trilogy", if you want to call it that, book one being bowery Boyz I beleiv, about a healer witch in a modern day city slum who does not return until the second half of book three, summoned to tourney....and of course Lackety then continued on with a second "trilogy" on bard eric's life alone after she managed to get rid of the other two main characters in Knight of Ghosts and Shadows. Rather funny, it was...first, a tripod was the strongest thing in nature, and then POOF, the beginning of the first book in the second "trilogy" disposes thoroughly of the idea.
It could be read as an object lesson in ignoring conditions you yourself set up in writing, I suppose, as well as a historical reference.
The book itself is decent, as is its antecendent and sequel, I'd just advice not to read these three and the second three after Lackey breaks up her threesome. Pick one or the other, instead.
