It’s not my genre, but I think just based on the title and subtitle, it sounds like a cool story. maybe even in the murder/mystery genre. It sounds intriguing.
However, it’s a little confusing when the first three words are ‘rules and guidelines’. Of course, the rest of title clears that up, but perhaps choosing different words to make it sound more dynamic would be better?
The main problem I have with the cover are the font styles used. i can barely read the sub title and the effect of three different fonts used on the title isn’t the best in my opinion. the background could also be a better image, perhaps one more red than brown, with a higher saturation and contrast? The composition is also a little too much to the left side.
(I realize the copyright is still there, but then the background is not my image DX)
