When Katara and Sokka, two children of the South Water Nation Tribe, discover a perfectly preserved and mysteriously alive, girl inside a huge sphere of ice, their lives change forever. This girl is the now mythical 'Avatar', the only human being in the world who can bend all the elements: Water, Earth, Fire and Air, and commune with the spirits. Now, the Avatar must accept her destiny, and save the world.

This is a very old Underland fairytale--so old, nobody knows who wrote it. It resembles the story of Ares and Belle, or her ancestors Alice and Nat. This is the story of Beauty and the Beast--or rather, Beauty and the Bat.

With two prophecies fulfilled, Belle is now focused on the Prophecy of Blood, which calls for Gregor and "the princess", Boots, to return to the Underland to help ward off a plague. But someone new is coming this time...Gregor's mother. The plague is spreading violently across the city, and not only is one of Gregor's family stricken, but also one of the people Belle loves most. Belle realizes what she and Gregor must now do. They must summon all their power to end the biological warfare, or the warmblood creatures of the Underland, will die.

Everyone has been trying to keep Belle from seeing The Prophecy of Time. That is because the final prophecy calls for a female warrior's death. With an army of rats quickly approaching and time running out, Belle must defend Regalia and help Gregor get his family home safely. There is a code that must be cracked or all will be lost. It is a war designed to end all wars. The fates of the Underland and the great warrior, Belle the Overlander, unfold in the latest installment in the Underland Chronicles.

Now, with the third prophecy fulfilled, Belle is drawn into a crisis. For generations, rats have run the mice--or "Nibblers"--out of whatever lands they've claimed, keeping them on the move. But now the mice are disappearing, and the young queen Luxa is determined to find out why. When Belle joins her on a fact-finding mission, the true fate of the mice is revealed. It is something far more sinister than Belle or Luxa could have imagined--and it points the way to the final prophecy that has yet to be fulfilled. Will Belle's role as one of the Warriors and her newfound 'trancing' abilities be put to the test?

Months have passed since Belle first met Gregor the Overlander, and her life has since been uneventful. But she and Gregor are destined to be key players in another prophecy, this one about an ominous white rat called the Bane. The Underlanders know that there's only one way that Gregor will come back: if they kidnap his little sister, Boots. The quest reunites Gregor with Belle, Luxa, and his new bond, Ares. They descend into the deadly Waterway in search of the Bane. If Belle and Gregor do not fulfill the prophecy, their lives, and the Underland, will never be the same.

When eleven-year-old Gregor and his little sister Boots fall through a grate in the laundry room of their New York City apartment, they hurtle into an underground world they never knew existed. Fourteen-year-old Belle meets the pair in her home, the Underland, where humans live uneasily beside giant spiders, bats, cockroaches, and rats. But their fragile peace is about to fall apart. Belle and Gregor must take part in the Prophecy of Grey to stop a horrific war, and save the Underland.
