When Friday Barnes cracked the case of Highcrest Academy’s mysterious swamp-yeti, the last thing she expected was to be placed under arrest. Now with the law on her back and Ian Wainscott in her face, Friday is not so sure boarding school was the smartest choice. From a missing or not-so-missing calculator to the appearance of strange holes in the school field, she is up to her pork-pie hat in crimes – and she swears not all of them are hers. There’s also new boy Christopher, who has taken quite a shine to Friday, to contend with.

Can Friday navigate the dangerous grounds of Highcrest Academy and decipher a decades-old mystery without getting caught in an unexpected love triangle?
