No one has ever accused Sage Cunningham of being easily distracted. In fact, her best friend Ellie only wishes she could distract Sage from her schoolwork sometimes—but Sage has a plan, and she won’t be swayed. She’ll spend the summer interning in her mentor Dr. Reese’s lab in Amsterdam, and then she’ll be ready to start her freshman year at Johns Hopkins. All she needs to do to pay for the summer abroad is agree to serve as the au pair for Dr. Reese’s three-year-old as well. Sage has it all down to a science, but she doesn’t anticipate the surprise arrival of Dr. Reese’s teenage son. Ryland is spontaneous, loud, and impulsive—everything Sage isn’t. He’s an artist, and he’s not half bad, but he’s desperately in need of someone to keep him focused. And as work ramps up and nannying proves harder than Sage had expected, it turns out she might need help too. The two strike a deal. Sage will stop Ryland from going out with a different girl every day, and Ryland will pitch in with his little brother. Spending the whole summer stuck together is the perfect way to keep distractions to a minimum. Right?
