I absolutely love the cover! It would definitely make me pick it up at a book shop. I adore how colourful, yet simplistic it is. In terms of the description, I think it’s a great insight into the book but is a little bit dull. It could be improved by mentioning the challenges of the psychological experiment and any difficulties and hardships Hildy and Paul face. Apart from that, I think the description is great and has no inherent problem. The cover could possibly be improved by including some kind of reference to the psychological experiment as the cover really doesn’t have any reference to that. It may also influence people who are interested in psychology to notice the book, pick it up and purchase. So overall there are just minor details in regards to how the cover and description can be improved based on my opinion. I really hope this helps!
