Ben Bellini didn't mean to become a champion speller--after all, he's not a nerd--but he sure does like spelling bee glory now that it's found him. He might even be good enough for the Scripps National Spelling Bee in Washington, DC! And what better way to prepare than to train with a professional spelling coach in San Francisco, where his nan lives?

Through his adventures, Ben gets to know the city--and competitor Asha Krishnakumar, who's equally determined to spell her way to victory. But Ben also starts having odd interactions with his nan that leave him feeling like he's missing something. Where is Nan's forgetfulness coming from? And will anyone even believe him if he tries to get help?

Between showing up for his loved ones and pursuing his own dreams, Ben will need to spend this summer figuring out what he owes others...and what he owes himself.
