@Nyrryl-Cadiz Thanks so much. Here's my description from the KS page:
Doriane Valentine has always found it difficult to fit in. When her step-dad, Tom, lands the job of caretaker at Gullmuir, a derelict house in the middle of nowhere, she is ready to go. Doriane’s mum, Marta, is unable to communicate due to a condition she developed when Doriane was small, she spends all of her time looking out of the window. Convinced that things will be better for all of them at Gullmuir, they leave their old lives behind.
Doriane’s first instincts tell her to look for spirits and mysteries to solve, but everything appears normal and boring. Finding herself a study, she settles in and draws a cute ghost on the condensated window. Later when she tries to rub it away, the ghost won’t budge and tries to communicate with her. When Tom leaves Marta’s pills in her study, a negative reaction from the little ghost causes Doriane to investigate and take affirmative action that changes all of their lives forever.
