The Kane Chronicles Collection 2 Books Set by Rick Riordan The Serpents Shadow, The Throne of Fire
The Serpent's Shadow
He's b-a-a-ack! Despite their best efforts, Carter and Sadie Kane can't seem to keep Apophis, the chaos snake, down. Now Apophis is threatening to plunge the world into eternal darkness, and the Kanes are faced with the impossible task of having to destroy him once and for all.
Unfortunately, the magicians of the House of Life are on the brink of civil war, the gods are divided, and the young initiates of Brooklyn House stand almost alone against the forces of chaos.
The Throne of Fire
Ever since the gods of Ancient Egypt were unleashed in the modern world, Carter Kane and his sister, Sadie, have been in trouble. As descendants of the House of Life, the Kanes have some powers at their command; but the devious gods haven't given them time to master their skills at Brooklyn House, a training ground for young magicians. And now their most threatening enemy yet--the Chaos snake, Apophis--is rising. If they don't prevent him from breaking free in a few days' time, the world will end. In other words, it's a typical week for the Kane family.
