Max Einstein saves the future - James Patterson

Max Einstein is never going to be your average 12-year-old kid. She . . .
is on the run from a group of villains
talks to Albert Einstein
spends time searching for information on her parents
saves the world with the help of her genius friends

Totally not ordinary stuff - unless you're Max Einstein!

Now Max and her friends are back and ready to take on their biggest problem yet: world hunger. While the Change Makers tackle this huge issue, Max must also avoid the evil Corp and her nemesis, Dr. Zimm. But they're not the only ones looking for Max, and as she finds herself on the run, she discovers that Einstein created a time machine. And it might give her clues to her past - her distant past . . .
