Book description
After a break from their trips in the tree house, Jack and Annie are
delighted to find that it's back! Morgan le Fay needs their help, but
they'll have to become Master Librarians first, and that means solving
four riddles. For the first one, Morgan sends them deep into the middle
of the ocean. Jack and Annie ride in a mini-sub and meet jellyfish, sea
horses
and
an octopus. But there are some scary sharks in the deep and the
friendly dolphins have to come to the rescue. . . Mary Pope Osborne is
