Apparently, these recent Thrawn novels are being considered a trilogy. The one that came out this week is reviewed below. Also, this is my 501st book read over the past 16 summers; SW numerology!
Much as I hate to say it, this Zahn novel was just simply okay. There are several good parts, mainly towards the end (a cape saves the day!, Thrawn defeats an opponent from the bridge of that Imperial's own Star Destroyer, that species to fear from "out there" [that once was the Yuzzan Vong, but I guess not anymore] called the Grysks has impressive technology and aggressive tactics, Thrawn uses someone's music as art to analyze the tendencies), but overall it just dragged as a plot. Thrawn knows EVERYTHING, and aside from the "one-of-these-days-that'll-bite-you" warning given to him at the end it's almost unrealistic. No real "surprises" for me. It leads right into the last episodes of the Rebels TV show.
