Friday Barnes, Girl Detective (Friday Barnes Mysteries)

When Friday Barnes, girl genius, solves a bank robbery, she uses the reward money to send herself to Highcrest Academy, the most exclusive boarding school in the country―and discovers it's a hotbed of crime! Soon she's investigating everything from disappearing homework to the terrifying Yeti haunting the school swamp. But the biggest mystery yet is Ian Wainscott, the handsomest (and most arrogant) boy in school who inexplicably hates her. Will the homework be found? Can they ever track down the Yeti? And why is Ian out to ruin her?
