Yes, I like the looks of this installment. Each of the last three chapters has been a nice mix of combat, exploration, role-playing and skill challenges, IMO. I also like that the title page illustration shows the treat up front, but the real villain only in silhouette. I think my party will be able to keep their heads, even when expected to act civilly to evil creatures and make deals with them.
Not sure how I feel about the githyanki's ambassador. Since the last time he was seen, the adventure assumed the heroes didn't discover anything about his treachery and he hasn't been mentioned since, I think it will come a bit out of left field. "The ambassador is *who*? I guess I remember him a bit..... Wait, when did he betray his people? From before we met him? Why did he act the way he did the last time we saw him?" Et cetera....
