When fourteen-year-old Noah falls from the trees on his classmate Sahara, he doesn't understand how, or why, he would have been up there. It's just one more in a string of strange things happening to Noah lately. Like when he keels over and every muscle in his body freezes when confronted by bullies. And when he vanishes into the background at a moment he doesn't want to be noticed. And when he unexpectedly blasts Sahara with a bird shriek while flapping his arms uncontrollably in the middle of a school dance. What does it all mean? And why do there suddenly seem to be so many mysterious people trying to kill him? Noah's friend Ogden has an idea...but like all of Ogden's ideas, it's out there. Way out there...
