Maggie Blue is adjusting to a quieter life, back living with her aunt Esme and hanging out with friends Ida and Will as well as her beloved Hoagy the cat. She tries to forget about the events of the previous year - but she's being watched, and one day a small white bird appears. Where has the white crow come from, and why won't it leave Maggie alone? Little does she know that the Dark World is waiting for her to return... and when her mum is kidnapped and taken there, Maggie only has no choice but to go back. With the help of Hoagy and some new friends by her side, Maggie must go back to the place that she never wished to see again, if she's ever to see her mum - or gain control of her own life - again.
