Set of the first two books of the Inheritance series - Eragon and Eldest.  Ideal for kids of all ages.

Eragon tells the story of a young farm boy named Eragon, who finds a mysterious stone in the mountains.  A dragon he later names Saphira hatches from the stone, which was really an egg.  When the evil King Galbatorix finds out about Eragon and his dragon, he sends his servants, the Ra'zac, after them in an effort to capture them.  Eragon and Saphira are forced to flee from their hometown, and decide to search for the Varden, a group of rebels who want to see the downfall of Galbatorix.

Eldest begins following several important events in Eragon.  The story is the continued adventures of Eragon and his dragon Saphira, centering around their journey to the realm of the Elves in order to further Eragon's training as a Dragon Rider.  Other plots in the story focus on Roran, Eragon's cousin, who leads the inhabitants of Carvahall to Surda to join the Varden, and Nasuada as she takes on her father's role as leader of the Varden.  Eldest ends at the Battle of the Burning Plains, where Eragon faces a new Dragon Rider, Murtagh, and a new dragon, Thorn.
