The Maze of Bones (The 39 Clues) Steaminess Rating

Exactly how steamy is this story?

G

This is a story about an eleven- and fourteen-year-old brother and sister in a race around the world. It has about as much sex as you'd expect in an episode of Amazing Race: Family Edition. That is to say, there isn't any. Aside from eleven-year-old Natalie Kabra dressing way too old for her age, looking like "eleven going on twenty three" (16.55), there is no romance, no innuendo, no sexual desires whatsoever in The Maze of Bones.
