When conventional Agnes Evans loses her younger sister, Tilly, in a car crash, she must confront the fact that she knew precious little about her eccentric sibling.  Filled with guilt, Agnes discovers Tilly's Dungeons & Dragons notebook, which sends her on a journey into her sister's lively imagination.  In Tilly's world, Agnes must confront not only the monsters of the game, but also those of her own making.  A fantastical celebration of geekdom, She Kills Monsters is an action-packed comedy with heart.  Adult themes and content.  Not recommended for children.
