Create a video book trailer using the digital tool of your choice.
You can, for example, make a presentation with google slides/powerpoint/Canva and make a screencast recording (screencatify, loom,...) or ask some friends for help to act out it out and make an actual video recording.
Remember to include music to set the tone, and tell a brief story about the central conflict and characters without revealing too much! Tease the audience! Sell your book!
