National Book Award winner Kathryn Erskine delivers a contemporary story about a boy with a mystical worldview and a love of science and comets as he faces questions about what makes him special.

Some might say Julian is sheltered. But he lives large, and his eternal optimism allows him to see infinite possibilities wherever he looks. Despite his optimism, he is anxious about his stressed family falling apart. Even his ability to "uni-sense" what's happening with his sister is gone. If he can make his family focus on the magic in the universe, surely they'll appreciate life again. Now that they are moving from Washington, DC, to rural Maine, Julian can use his beloved telescope without any light pollution. He can discover a comet, name it for himself, and show his family how they're all truly connected.As Julian searches the night sky, he encounters a force that may drive his plan apart. His neighbor, Mr. X, could bring an end to his parents' dream of opening their B&B. Could one negative force unravel everything? An avid student of science, Julian understands that there is much about the universe that we don't yet know. Who is to say what's possible and what's not?
