Gwen's death was actually quite PG, compared to some books that are aimed at younger audiences that i've read. She was described to look like she was holding her pilum between her arm  and chest, except for the fact that there was too much blood. Now, I'm not saying that wasn't a violent death (even though she comes back to life later) but there are kids books where the deaths are described in much greater detail than "There was too much blood."
