Greek Gods and Heroes is one of the better books on mythology for children out thare, with great pictures and easy to understand stories that people of all ages can enjoy. As a child it was my favorite book in the school library and I checked it out over and over again. It is a must have for any fan of the greek gods and the myths about them.

Positive
