this was WAY BETTER than it had ANY RIGHT TO BE! one part moving story about friendship and forgiveness, one part interdimensional sci-fi epic, and like, twenty parts awesome punching and goofy comedy. The plot twist at the end was actually perfect, with smaller twists along the way that were totally unexpected and offer some fun insight into both universes. Plus the whole thing is littered with Easter eggs for folks who love the shows. I can wholeheartedly say I’d recommend this to any reader, any age. A fun and smart read all the way through.
