4 boys, 3 days, 1 castle. What could possibly go wrong?
This is the final book in the 3-book Markree Castle series (and the 4th book in the Li & Lu series). You think that's confusing, wait until you learn how to say Donald Duck's nephews in Chinese.
That kind of extremely useful knowledge (and more) awaits you throughout the pages of the Markree Castle series. So jump on in and enjoy!
