From the publisher:
A brand-new Bob Books set for pre-readers! In 12 books of 12 pages each, children are introduced to the alphabet. When they finish with these books, they're ready for Bob Books Set 1!
Expanding on the core sets that have made Bob Books such a success, the Alphabet Set includes 12 books of 12 pages each, and brings Bob Books' proven teaching tools to children who aren't quite ready to read Set 1 yet. The letters of the alphabet are introduced in a fun, easy-to-understand way as only Bob Books can!
