Brook Berry in The Case of Myst River is a fantastic book. It has excitement, a great pot twist, and is great for a young children's mystery book. Being the age of 12+, the book was quite an easy read but was very enjoyable. The characters were described very well, being someone who hasn't read the first or second book. This book kept me on the edge of my seat even though the plot was a little predictable. If I was younger, the book would have been more exciting. But overall, this book is great for a kid ages 7-12 who wants a fun, Scooby Doo/Hardy Boys/Nancy Drew type of book.
