Edith Nesbit is considered the first modern writer for children. I love her tales in The Book of Dragons. That and many of her works are available for free at Project Gutenberg.

…the next day he wanted another look, so he took the book out into the garden, and when he undid the clasps with the rubies and turquoises, the book opened all by itself at the picture with “Dragon” underneath, and the sun shone full on the page. And then, quite suddenly, a great Red Dragon came out of the book and spread vast scarlet wings and flew away across the garden to the far hills, and Lionel was left with the empty page before him, for the page was quite empty except for the green palm tree and the yellow desert, and the little streaks of red where the paintbrush had gone outside the pencil outline of the Red Dragon. And then Lionel felt that he had indeed done it. He had not been King twenty-four hours, and already he had let loose a Red Dragon to worry his faithful subjects’ lives out. And they had been saving up so long to buy him a crown, and everything!-Edith Nesbit, The Book of Dragons
