Countdown hook
Open on a ticking clock and the stakes in one sentence.
Example hook: “She has 48 hours to prove she didn't do it.”
Evidence board
Show clues pinned on a board; ask viewers who did it.
Example hook: “Four suspects. One lie each.”
Unanswered voicemail
Use a fake voicemail or text as the hook (clearly fictional).
Example hook: “1 new voicemail: 'Don't come home tonight.'”
Twist meter
Rate your book on twists, pace and dread without spoilers.
Example hook: “Twists: 4/5. Sleep lost: all of it.”
First line
Put your first line on screen, nothing else.
Example hook: “The first line of my thriller. Would you keep reading?”
Suspect lineup
Introduce suspects in one line each like a police lineup.
Example hook: “Meet the suspects.”
Real research
Share an interesting (true) bit of research you did for the book.
Example hook: “I spent a week learning how forensic accountants work.”
Read it if…
List the moods your book delivers: unreliable narrator, locked room, revenge.
Example hook: “Read it if you love unreliable narrators.”
Chapter-ending cliffhanger
Read a chapter's last two lines and cut to black.
Example hook: “This is how chapter 3 ends.”
Night reading challenge
'Try reading the prologue at night' style hook with a moody setup.
Example hook: “Don't read this prologue alone.”
Tips that apply to every idea
- Put the hook on screen in the first second — many people watch with the sound off.
- Keep one idea per video; 15–30 seconds is plenty for most of these formats.
- End with one clear action: 'link in bio', 'comment your pick', or 'follow for part 2'.
- Batch-make a week of clips in one sitting, then post on a schedule you can keep.
