Secondhand Life by Pamala Crane
This thriller offers strong exposure opportunities for anyone working through emetophobia. Throughout the story, vomiting is referenced multiple times by several characters, including the protagonist and the killer. Scenes include active vomiting, nausea, gagging, and repeated mentions woven into emotionally intense moments.
Because the content appears often and sometimes suddenly, this book can provide practice with:
Unexpected vomit references
On-page vomiting
Physical descriptions of nausea or gagging
Multiple characters vomiting across different contexts
A solid pick if you're looking for higher-level exposure with recurring triggers while still engaging in a fast-paced, twisty mystery.
