I'm not sure specifically as there could be many interpretations. It might be about a baby named Thomas in a glade, perhaps with some sort of adventure or discovery in that setting.
Survival is a common theme. Since she's in the glade, she has to figure out how to find food, water, and shelter. Another theme is mystery. The glade itself is often portrayed as a place full of secrets. For example, there could be hidden passages or unknown powers.
