Chloe Ellis and her friends are back for their second year of school at Hogwarts! But as the days draw closer to September 1st when the Hogwarts Express left for the school, she gets a strange warning from a House Elf who called himself Dobby. He warns her about the dangers that could be at Hogwarts during the year. But every time she'd try and ask what was going to happen, he'd bang his head against anything to punish himself. At Hogwarts, Harry starts to act oddly and not his usual self. Voices could be heard by Chloe in the walls of the school. A giant spider attacks them. They find a ghost girl that went by the name Moaning Myrtle, who was mysteriously killed in the blocked-off girl's bathroom. She finds a diary that could talk to her in some ways, giving her the wrong information. History repeats itself again, and Chloe must do everything she can to keep the school safe.
