NOTE: This is a guidebook of Pokemon, not a plot-centric story.
Thoughts on Ash & Pikachu: Alola Region:
Interesting look at some of the Pokemon found in the Alola Region. Each Pokemon is described by category, height, weight, and type as well as a short blurb with other unique abilities. Many of the evolutions of the Pokemon are also included in the book. Nice illustrations. Good for those who want to learn more about specific Pokemon.
Thoughts on Team Rocket: Alola Region
Similar in style to the Ash & Pikachu version, this book also lists Pokemon and their category, height, weight, and type along with other pertinent information. The only Pokemon repeated in both books are Pikachu and Lycanroc (midday form and midnight form), but some different information is given so it is not too repetitive.
Overall, good books for those who want to learn about Alola region Pokemon.
