Princess on the Brink by Meg Cabot

It’s the start of junior year and Mia is back from Genovia and busy preparing for the PSAT (why does it include math. Doesn’t Genovia have accountants for that??), trying to avoid Lilly’s attempts to make her run for student council president, and princess lessons (of course). She’s looking forward to finally seeing her boyfriend Michael (dinner at Number One Noodle Son!), but his plans for the year throw her for a loop. During the summer Michael created a prototype of a robotic arm that can be used to perform open heart surgery. His professor was so impressed that now a company in Japan wants Michael to come and assist them with building the actual thing. And it could take at least a year or more. WHAT!!!!!!!!!!! Mia is torn between the good (saving people’s lives) that could come from Michael’s invention and being without him for a year. She’s desperate to find a way to make him stay in New York. In typical Mia fashion, things don’t go according to plan and now everything has changed.
