This "novel" (novella) essentially reads like a long episode of the Netflix series, though I was confused as to when it was supposed to be set, since Shadowsan was no longer a member of VILE but wasn't working with Carmen (and was never even mentioned by name). Aside from the sometimes poor prose, the reason I knocked off a star is that Otheguy didn't capture the characters particularly well. Ivy and Zack's dialogue in particular sometimes sounded out of character.
That being said, the adventure itself is good, and while the info-drops are irksome, they're at least handled a bit better than in the show. (Not that they could be much worse.) For the show's fans, there's also a little bit of Player's history revealed. And while Argent and Devineaux are absent, as is Tigress, we get to enjoy rather a lot of time with my favorite minor character, Paperstar.
But what really impressed me was the way the book addressed biracial identity and colonialism. These are topics not often addressed in kids' genre fiction, and Otheguy (or the powers that be) handles them simply, perhaps simplistically, but clearly. While the show occasionally tries to broach difficult topics, it usually ends up brushing past them to get on with the action, but here they're an inherent part of the story.
As a lifelong Carmen fan, I'm still unhappy with the direction Houghton Mifflin has taken with the franchise, but taking that for granted, I think this book shows where the concept could be taken with some social awareness. I hope that awareness will become more a part of the show and the books moving forward.
