When Anya, a teenager who is uncomfortable with everything from her body to her Russian family, falls down an abandoned well, she is surprised to discover she is trapped with the skeleton of a girl...along with her ghost. While Anya eventually escapes the cold, dark well and resumes her normal life, she feels guilty for leaving the lonely mysterious ghost, Emily, behind. By taking a piece of Emily's skeleton with her, the ghost is able to leave the well and experience life with Anya. At first, Anya is enjoying all the perks of having a spiritual sidekick, until she suspects that Emily has a darker past than she previously thought.
When Emily becomes too involved in Anya's love life, she decides to bring her bone back to the well so she can live in peace again. But there's one problem, Emily is no longer a lonely ghost; she has her own motives, desires and has even learned how to move physical objects. This quirky story takes a dramatic and creepy twist when Anya must find out who Emily really is in order to banish her back to the well. While an interesting, illustrated take on a classic ghost tale, Anya's Ghost is also a touching coming-of-age story about self-acceptance. The muted purple color pallete that Brosgol uses to illustrate the story gets increasingly darker as it progresses, perfectly complimenting the darkening plot.
