An analytical project. Truth in Romance examines and quantifies how explicit-romance fiction is constructed — including the explicit passages themselves. It contains adult content and is intended for readers 18 and over. Every book in the catalog is illustrative and fictional — titles, authors, and the metrics attached to them are invented to demonstrate the analysis, not to describe real published works. Industry figures are attributed to published industry research (Circana and similar).
