This will be available on my website.... as my eBook 'Trust First, Fundraise Second' is... https://www.getyourstoriesstraight.com.
So I want to to look like a real business book, a classic serious non-fiction design... with depth provided by an image of Silicon Valley.
The concept here is that the front cover should be an aerial shot of Silicon Valley (or any flat plain, with modern looking building and a mountain on the other side) with blue sky above it where the Title and authors name are written on the blue sky.
I've uploaded an imperfect screenshot below, which should help you get the general idea. But I'd imagine you've seen this done before. It's a popular approach, especially with women's fiction.
Lastly, I'm not sure how to achieve this in a subtle way, but i'd almost like for it to feel like the headline (and the secrets) were floating or coming out of the valley below. To give the headline some physicality and create that connection between text and image.
This sounds a little wacky, I know, but hopefully it inspires you a little!
