Morgan le Fay will make Jack and Annie masters of the tree house if only they can solve four riddles. "Dolphins at Daybreak" begins the third set of four books in the magical series, as Jack and Annie embark upon solving riddle number three in a whole new world under the ocean!

Good moods, bad moods, can't-stand-Jessica-Finch moods. Judy Moody has a mood for every occasion, and this time she's in a jealous mood. Jealous of Jessica Finch, that is, who gets her picture on the front page of the newspaper. When Judy sets off in pursuit of her own fame and happiness, watch out!

In this exciting adventure, Jack and Annie are taken to a monastery in medieval Ireland to find a lost book. While they are there, Viking raiders come ashore, hoping to make slaves of the monks.

The Magic Tree House whisks Jack and Annie to the decks of that ill-fated ship, the "Titanic". There they help a toddler find her way to a lifeboat before they, themselves, are in grave danger of becoming two more victims of the tragic event.
