Book Review: The Serpent's Shadow by Rick Riordan
There is possibly one way to stop Apophis, but it is so diificult that it might cost Carter and Sadie their lives, if it even works at all. It involves trusting the ghost of a psychopathic magicians not to betray them, or worse, kill them. They'd have to be crazy to try it. Well, call them crazy.
Ivy's summary: Carter and Sadie have been training to defeat Apophis and learning magic spells. They also have to follow the path of the ancient gods. They have to restore Ma'at to the world and stop the evilness around it.
See I told you the third book was so far better. It have more action to it and so does The Throne of Fire.
