The Time of the Ghost

From The Other Wiki: "The Time of the Ghost is a 1981 novel by British children's author Diana Wynne Jones. It is about a ghost who observes four sisters, knowing she's one of them, but can't remember which one."

The four Melford sisters - Charlotte (Cart), Selina (Sally), Imogen and Fenella - live in a house attached to the boarding school their parents run. Their parents pay very little attention to them, to the point of neglect, and the girls behave in wild and occasionally outright dangerous ways.

The girls worship a doll called Monigan as a game, but it turns out that Monigan is real, and seven years from that time will take the life of one of the sisters. Can they stop her in time?

Tropes featured include:

 * Abusive Parents - Mostly through neglect, which is still pretty bad:
 * Not having any food in the house is treated as a regular occurrence. When the girls take food from the boarding school's kitchen, the cook - and their mother - scolds them, though they don't have anything else to eat.
 * Through a large part of the book, neither parent realizes one of their daughters is absent.
 * Fenella ties her hair into knots to see how long it would take her parents to notice.
 * Adults Are Useless - The parents are neglectful at best and Mrs. Gill, the boarding school's cook, isn't helpful at all.
 * An Astral Projection Not a Ghost: The ghost turns out to be one of these.
 * Balancing Deaths Books - Subverted with . Played straight
 * Beware the Nice Ones -, the most normal looking sister,
 * Jerk in Sheep's Clothing - Julian, who ended up
 * Boarding School - The Melford parents run one.
 * Creepy Doll
 * Goddess of Evil - Monigan.
 * I See Dead People - Played with;
 * Quest for Identity
 * Reality Subtext - The scariest thing about this book is that half the horrible things that happened to the sisters happened to the author and her sisters as kids.
 * The incident with one of the sisters almost getting hanged with a skipping rope happened; one of Diana Wynne Jones' yougner sisters tied her hair in knots of keep it out of her eyes, amongst others. Interestingly, a lot of people found it implausible that so long went by in the book before anyone noticed the latter, but in reality it was months.
