The Rolling Hills - page 1 (of 4?) by Shannon Dybvig
Fair warning: this particular comic, though short, may be a little (or a lot) distressing. If you are sensitive to topics relating to pregnancy, specifically miscarriage/losing a child/strange happenings, I would strongly recommend either not reading it or having someone you trust read it first. This is the only page posted so far, but I will post another warning when the full comic is up.
