Saatchi Online Artist thomas saliot; Painting, "Close up water". Drawing images that are dripping or wet would be interesting. Could teach them a lot about how light reflects on water streaks or drops. Students could bring in their own pictures.
New York Times best selling book The Shack is an analogous tale that cuts to the heart of the issue of human suffering and our relationship with God. Don't be scared off if you're not 'religious'. There's nothing religious about this book which is probably why it's a NYT best seller :)
