When Aideen agrees to help ambitious class swot Maebh Kowalska deal with her crazy workload, she doesn't expect to end up reluctantly pushing Maebh down the stairs. With this, Aideen becomes the school 'fixer': any problem a student has, Aideen will sort it out, from stealing confiscated mobiles to breaking into parties. All she asks for is a favour in return. But Aideen's own life is a mess - her mam's drinking again, her BFF Holly is avoiding her and she's skipping school. Spending more time with the uptight (but annoyingly cute) Maebh and chatterbox Kavi, Aideen starts to wonder: can every problem be solved?
