It didn't grab me quite as much as say The Prestige or The Affirmation, but I have to agree with others that it's quite brilliant. It ties together some of the themes and worlds of his other work into a very satisfying novel. I also found it a little more coherent than some of the author's other works so there's more of a payoff that doesn't require multiple re-reads. Not to say that a re-read is not a enjoyable endeavor with Priest. Those new to Priest may not get as much out of The Adjacent, but fans should enjoy it quite a lot. Will definitely be one of my top reads for this year.
