King and Kayla is a great beginning reader series. King tries very hard to make Kayla understand what he is thinking, but she never does. Each story (Case of the Missing Dog Treats and Case of the Secret Code, Case of the Lost Tooth expected March 1, 2018.) involves a small mystery that King has to work through. Each mystery is simple enough that readers can figure it out with a little help. I have fond memories of reading the Encyclopedia Brown mysteries with my mother and working with her to figure out how to solve each one before checking the answer at the back of the book. These books would be good for that activity.
The artwork is simple and clean, and the dog's faces are particularly expressive. This helps a lot when Kayla isn't sure what King is thinking-- we know, because we can see the answer right in the dog's eyes! It's good to see Kayla on the front cover; there's no particular reason for her to be African-American, but there's no reason for her NOT to be, either. There aren't a huge number of early chapter books with children from a variety of cultural backgrounds, but there are a few.
Readers who enjoyed Warner's Absolutely Alfie, Draper's Sassy, English's Nikki and Deja and Mills' Izzy Barr will be delighted with the antics of Kayla and her adorable pet.
