This book has a number of flaws but it does one thing well - the author is very inventive in creating a zoo of fantastic/magical animals. Those passages describing the animals, their behaviour and their enclosures are the best part of the book. She also seems to be rather knowledgable about the work behind the scenes of a zoo. If you're in any part critical of zoos, though, this book would be very frustrating. The only criticism is only presented once and is rather superficial. I appreciate the effort of the author to make the protagonist someone with anxiety but unfortunately, she comes off as rather annoying and also immature for someone her age for about half of the book. There thankfully is some character growth eventually. The pace picks up at around the halfway mark and while the mystery turns out to be somewhat predictable in the end, I enjoyed the book overall. Objectively, it only merits 3 stars but it felt more like 4, so I'll settle at 3.5.
