In her third adventure, Cookie finds mysteries everywhere - but can she solve them, and save the science show?
Hurray, Cookie´s Nani is coming to stay from Bangladesh! But she doesn´t speak English and Cookie is the only one in the family who doesn´t speak Bengali. Luckily, science-mad Cookie realises that her coding lessons at school might help her crack the language code and help her bond with Nani.
Other mysteries are harder to solve, though - like, why is Jake´s mum acting so weird? Who is the mystery gamer who keeps levelling-up in Cookie´s computer game? And who is the Woodburn Hacker, who keeps posting teachers´ secrets on the school website? Why does it look like it might be Cookie herself?
Can Cookie solve these mysteries, clear her name and save the science show?
