Four mythical Elementals Water, Land, Air, and Fire have the power to save two worlds, Earth and Farworld, from a common enemy: the Dark Circle. In book one, Water Keep, a portal has been opened between the two worlds, allowing Marcus, from Earth, and Kyja, from Farworld, to combine their unique gifts and begin their epic quest to find the Elementals. In book two, Land Keep, Marcus and Kyja travel with Cascade, a Water Elemental, toward Land Keep, the home of the powerful and wise Land Elementals. However, their journey may end before it even begins. Land Keep is empty, deserted for at least a thousand years, and the rumor is that the creatures who once controlled all land magic are extinct. Marcus and Kyja's only hope seems to lie in finding the Augur Well, a legendary Oracle protected by subtle traps and mind-bending trials. To succeed in their quest, Marcus and Kyja must also avoid the Keepers of the Balance, an order dedicated to redistributing magic to the rich and powerful. And they must travel far underground, where Cascade is unable to follow and where they will be unable to leap to the safety of Earth. As the Dark Circle closes around them, Marcus and Kyja are faced with the temptation of what they desire most. Sacrifices must be made, and not everyone will survive unscathed....

Other people may see thirteen-year-old Marcus Kanenas as an outcast and a nobody, but he sees himself as a survivor and a dreamer. In fact, his favorite dream is of a world far away, a world where magic is as common as air, where animals tell jokes and trees beg people to pick their fruit. He even has a name for this place- Farworld.

When Marcus magically travels to Farworld, he meets Kyja, a girl without magic in a world where spells, charms, and potions are everywhere, and Master Therapass, a master wizard who has kept a secret hidden for thirteen years, a secret that could change the fate of two worlds.

But the Dark Circle has learned of Master Therapass's secret and their evil influence and power are growing. Farworld's only hope is for Marcus and Kyja to find the mythical Elementals- water, land, air and fire- and convince them to open a drift between the worlds.

As Kyja and Marcus travel to Water Keep, they must face the worst the evil Dark Circle can throw at them- Summoners, who can command the living and the dead; Unmakers, invisible creatures that can destroy both body and soul; and dark mages known as Thrathkin S'Bae.

Along the way, Marcus and Kyja will discover the truth about their own heritage, the strength of their friendship, and the depths of their unique powers....
