The Two Towers (Lord of the Rings Trilogy #2)

Sauron, the Dark Lord, has gathered to him all the Rings of Power except one -- the One Ring that rules them all -- which has fallen into the hands of the hobbit Bilbo Baggins. Young Frodo Baggins finds himself faced with an immense task when Bilbo entrusts the Ring to his care. Frodo must make a perilous journey across Middle-earth to the Cracks of Doom, there to destroy the Ring and foil the Dark Lord in his evil purpose.
