Nobody wants Tulip in their gang. She skives off school, cheeks the teachers, and makes herself unpopular with her classmates by telling the most awful lies.

None of this matters to Natalie. Natalie finds Tulip exciting, and at first she doesn't care that other people are so upset and unnerved by Tulip's bizarre games like Stinking Mackerel and Road of Bones. It's funny to watch their reactions, and there's always the delicious fear that the two girls might be caught. But as the games become increasingly sinister and dangerous, Natalie realizes that Tulip is going too far. Much too far.
