Having read a number of T.H. Lain's Dungeons & Dragons novels back-to-back in recent weeks, I've come to the conclusion this is a pseudonym for several writers working on the same series. This is very apparent in Treachery's Wake.
Whoever wrote Treachery's Wake clearly does not have the same grasp of the iconic characters as the "other" T.H. Lains demonstrated in The Living Dead and The Savage Caves, to name two. Gone is rogue thief Lidda's charming, smart-[aleck] banter. Gone are the quirks that made Elf wizard Mialee so appealing in The Living Dead, such as her allergy to alcohol, her raven alter ego and her bad eyesight (all completely forgetten and even contradicted in this book). The other characters are similarly miswritten.
But what I did not like most about this book is it reads more like a blood-thirsty action-adventure novel in the Executioner vein than a Dungeons and Dragons story. The book makes no bones about it: these adventurers are cold-blooded killers. They take life - monster and human - with nary a second thought. Mialee, in particular, reads more like a female Mac Bolan than a cultured Elf wizard who is hesitant to kill (as she is portrayed in other D&D series novels). Lidda spares a momentary thought for a number of innocent bystanders she kills at one point, but that's the extent of it.
Most unappealing is Orc barbarian Krusk, whose whole purpose in the book seems to be to act grumpy and kill people in the goriest manner possible.
The story's villain (who I won't reveal in order to preserve what little surprise this novel provides the reader) starts out interesting, but soon become nothing more than a one-dimensional character who -- once again -- resembles someone from the Executioner books more than D&D.
Maybe the person who used the Lain's name also writes for the Executioner series, because I saw so many similarities it's not even funny. With Mac Bolan, at least, such cold-bloodedness is expected, but in D&D while adventurers do have to kill 9/10 in order to complete a quest, they do so heroically. There is nothing heroic or even D&D-like about the way the iconic characters handle themselves in this novel.
If I had read this book first, before any others in the D&D series, I would have been turned off the whole series. As it is, I look upon Treachery's Wake as some sort of non-canon nightmare dreamt by Lidda or Mialee. If you haven't read a T.H. Lain Dungeons & Dragons novel before, this is NOT the book to start out with; even if you're reading them in order, it might not hurt to skip this one and come back to it only if some future D&D novel refers to the events in this story (as some of the books do have cross-continuity between them).
With any luck, time will show that this was an exception in an otherwise entertaining series of books.
