Trevor Henderson wrote the teen horror duology Scarewaves.
Notes on verification
Authorship and duology structure confirmed by multiple independent sources, but the claim's 'teen horror' descriptor is inaccurate — sources consistently classify Scarewaves as middle-grade fiction (ages 9-12), not teen fiction.
