The writing, the story, the action, etc. was all great, especially compared with the horrible previous installment in this series. The whole "Interlude" thing may have seemed a little strange to some people, but I'd seen the same exact thing before in Steven A. Roman's novelization of "X-Men: The Chaos Engine Trilogy," not to mention that it makes for much better reading than the completely separate yet intertwined stories that "Shield of Lies" had. I would say the ending seemed a bit Disney-fied, but you could say the same thing about the last scene of "Return of the Jedi" as well. I probably won't read this series again, but it still wasn't bad.
