Dragon Quest - Dragon Keepers, #1

Katira is living three lives. One as a big sister to her family who rely on her for everything, another as a servant in the royal castle and the third as a thief. When she is given yet another to add to the list it takes her on a hectic search to rob a dragon. The only person she can rely on for help is someone who has the power to destroy everything she holds dear. Will this quest be too much for Katira and will she have to return home empty-handed with her other three lives in tatters as well?
