Significantly less fun than the other books in the series (which I love! the series as a whole is one of my comfort reads), but not due to tackling any more complex or difficult issues in a decent way. Compared to the others, this book is boring and a bit puerile and, even, at times, offensive. It deals with Mia researching Asperger’s in an uncomfortably out-of-touch way, even for when the book was written.
