内容简介：
The Baobab tree leaned at a crooked angle, its trunk so enormous that you could easily fit a small, round hut inside of it. It was gnarled, twisted, knobbly, and an almost irresistible climb. When a strange and alluring creature vanished up into the tree, Tessa could not resist the urge to follow. But climbing the tree was forbidden, and her excuse, when caught, sounded too fantastic to be believed. She would have to prove it. Together with her friends, she returns to the tree. What they find is much more than the dangerous hollow tree that the Kays had warned them to stay away from. As they lower themselves into the dark interior of the Baobab, they quickly realize that there will be no turning back, and so they are plunged headlong and irrevocably into a most bizarre adventure.
