The Heirs of the Gods. Book 3. The Shadow of the Serpent

Everything that humans have achieved since the time of the pyramids may turn to dust tomorrow – for Apophis, the Serpent of Chaos, thirsts to destroy human civilization and our very reality. To stop him, Carter and Sadie Kane are... ready to do everything in their power. And even more. The young magicians must find the shadow of the serpent, trap it in an artifact, and then read a very complex spell. A mistake in it will cost the kids their lives… but this ghostly chance is better than none! Sadie Kane cannot decide which of the two guys she likes more. Carter worries that he won't be able to live up to the expectations placed on him… But these problems are nothing compared to the impending apocalypse! This time, master of teen fantasy Rick Riordan, author of the bestselling Percy Jackson adventures, has turned to the mythology of Ancient Egypt. This is the third book in the series.
