The Liar of Red Valley: Walter Goodwater

Don't trust the Liar.
Do not cross the King.
Never, ever go in the River.
In Red Valley, California, you follow the rules if you want to stay alive. But they won't be enough to protect Sadie now that she's become the Liar, the keeper of the town's many secrets. Friendships are hard-won here, and it isn't safe to make enemies.
And though the Liar has power - power to remake the world, with just a little blood-what Sadie really needs is answers: Why is the town's sheriff after her? What does the King want from her? And what is the real purpose of the Liar of Red Valley?
