I'd read a little of his stuff on the web and decided to try one of his books. This one is fantasy. The name soup at the beginning is a bit hard to deal with, but skim over it and go on. He owes a huge debt to Lovecraft's The Dream-Quest of Unknown Kadath--the youth's adventures are in that exact tone, until things start going south. Wright upends fairy-tale conventions about youthful adventurers, and mixes selkies, kelpies, storm giants, witchcraft, Eden, unicorns and Camelot into the plot as well (with a hat tip to Zelazny?).
The family charged with watching for trouble from within the dream-castle (moved from England to New England) has only two faithful watchers left: the grandfather and the grandson Galen. A warning comes, and you've three guesses which one sets out to learn what's going on. A crime repented too late, various treacheries, and overwhelming odds run up against layered defenses understood almost too late.
Wright goes into some detail about what selkie culture would be like--they are seal creatures that like to take human form by donning a human skin (and unlike the Wikipedia variety, skin humans to get their collection). Who is who, and who can you trust?
I didn't read the cover blurb carefully enough. This turned out to be book 1 of several. I guess I'll have to locate the others.
