Your child can name all twelve Olympians and wants more. Here is the thing nobody says out loud: the Greek myths are not children's stories. Every book on this shelf is somebody's decision about how much of them a child should get, and they draw that line in very different places. Two of these turn the gods into funny schoolchildren. Three tell the real stories with the darkness left in. One is a modern novel that only borrows the gods. Pick by your child's age and by how much of the real thing you want them handed, and reach for another whenever they are ready.
These are eight very different decisions about the same stories, and the differences are the whole point. Marcia Williams keeps every plot and gives up the grandeur, so a six year old gets all of Icarus in two comic pages. Heroes in Training and Goddess Girls are the gods redrawn as middle-school children with lockers and crushes, hugely fun and barely mythology, which is fine as long as you know that is what your child is getting. Donna Jo Napoli tells the myths straight and beautifully. The d'Aulaires' 1962 book is the canonical one many parents grew up on, complete and archaic and gorgeous. George O'Connor's comic is the one that keeps the sickle and the swallowed children. Roger Lancelyn Green, writing in 1958, is the hardest read here and the only one that makes the whole mythology hang together as a single story. And then there is Percy Jackson, which is a modern novel that uses the gods rather than a book of myths at all, and which is why half the children on this shelf are here. Reach for the one that fits the child in front of you tonight.
