Generate Titles for a Non-Fiction Book Proposal

The working title got you through the draft. The submission title has to do more. This gives you eight options across four styles, from says-what-it-is to makes-you-curious, so you can see the trade-off between being found and being clicked. For authors pulling a proposal together.
