A book trailer sells a book by creating the same pull the book does: intrigue, stakes, and a question the reader needs answered. For self-published authors, a short vertical trailer is one of the most effective ways to reach readers on BookTok and Bookstagram, where a great hook can move real copies.

The structure is hook line, premise, stakes, read CTA. Open with a single irresistible line (a question, a forbidden premise, a 'what if'), establish the premise and the world, raise the stakes without spoiling, and end by pointing readers to where they can get it. Mood and atmosphere matter as much as plot; the trailer should feel like the book.

Reelry turns your book into that trailer structure and produces the finished vertical video, with atmospheric visuals, a voiceover, and captions. You supply the premise; the tool builds the trailer.
