Still working my way through "100 Greatest Graphic Novels."
Anya's Ghost
by Vera Brosgol
2011 - First Second (Roaring Brook Press)
This is a young adult graphic novel, done in grayscale line art.
High school student Anya Borzakovskaya falls down an abandoned empty well, and makes a new friend of sorts - a ghost, a young woman whose skeleton has been down there 90 years. Initially her new friend is great company, but there's a darker side to her.
The book also has a rather large plug for the value of libraries - it makes sense in context, it's not just a non sequitur. As a librarian, I'm always happy to see such things ...
The art is simple but both effective and quite nice, and the story is good.
