Dragon Keepers #1: The Dragon in the Sock Drawer

For Magic Tree House readers who are ready for something longer, the Dragon Keepers series has the perfect length and reading level, along with the fast-paced writing, adventure, and sense of teamwork that kids love to read. TEN-YEAR-OLD COUSINS Jesse and Daisy have always wanted something magical to happen to them. So it's a wish come true when Jesse's newly found thunder egg hatches, and a helpless, tiny but very loud baby dragon pops out.
Soon the two kids are at the dragon's beck-and-call, trying to figure out what to feed her. An Internet search leads them to the library, which leads them back to the Internet, where they find a very strange Web site called "foundadragon.org." It is here that the cousins discover that the dragon's hatching has designated them "Dragon Keepers" and that not only do they have to feed her, but they have to keep her safe from the villainous Saint George who has kept himself alive over centuries by drinking dragons' blood.
