Hard Problem (Revised)

The Adventures of Emery Jones, Boy Science Wonder Book #2
From National Book Award-Winner Charles Johnson

It's the first day of middle school and nothing's going right for poet Gabby Sykes. She's in a bad mood, her hearing aid is missing, she's not allowed to eat cheese anymore for the rest of her life, and her best friend, scientific whiz kid Emery Jones, is already showing off . But things go from bad to worse when Emery's crush on a new student distracts him from dual threats to the entire world--self-replicating robots with minds of their own, and aliens intent on enslaving humankind. It's up to Gabby to snap Emery out of it, and fast. Together they team up with friendly robot Cal and former bully Chippy Payne--But will they be able to save Redd Foxx Middle School, and all of humanity, from destruction?
