Tumblerinas: Facing the Real World was an okay-ish story and the only book from the NuWho Adventures to feature Chin boy and Clala. I don't really remember much of it, I know that it was definetly better than The World is Saved by Jellybeans. It happens a day after Kennedy's death, 23. November 1963, so that's a fun nod, but also very unnecessary. Also, there's a clown called Wobblebottom.
