I don't think the first 6 posthumous collections suffer any serious diminution, though some of the work is "sketchy"--simply not up to Buk's previous standards; less body to them--more skeleton showing (THE NIGHT TORN MAD WITH FOOTSTEPS, 2001, takes, like, 200 pages before it hits it's stride)--but not so sketchy that it stopped me from enjoying the books. At SLOUCHING TOWARD NIRVANA, 2005, some serious problems begin showing--like the muddled, misplaced, clumsy writing, and often ungrammatical as well as solecistic language usage. COME ON IN, 2006, is a disaster. I mean, Martin making Buk sound like Rod McKuen is an insult to Buk; Martin making Buk sound like a bad writer is a crime.
