Intended to be used as an instructional tool to teach alphabetic and phonemic skills, this is one book in a series of twenty-six, with each book focusing on a specific letter of the alphabet.  If this were a tool being used in the classrooms of your school, it might be nice to have a set in the library for students to explore on their own, but as a stand-alone story it doesn’t reach much beyond adequate, and I’m not sure the cost of investing in the entire set would really be worth the dough.
