Quick, fun read
Format: Kindle
I purchased this because my son and I have been raising 2 albino axolotls since 2022.
The illustrations are very cute and well done. The story includes a few characters and even though it's so short, there is clear character development.
I would recommend this for children under the age of 8 to be read to. With repetition, they will easily be able to read this book (apart from those with reading challenges).
My 12 year old read it through in one sitting and added his own unique reading style to it which was really funny.
I wouldn't recommend reading this on a small screen as the font is small.

Great Start
Format: Hardcover
My 9 year old doesn’t like reading. When it’s time for him to read to us, this is his go to book. Chapter books are a bit intimidating for him. He is eager to read about Max and is wanting to ready without us asking. We are looking forward to book 2.
