I think the cover is adorable. Each of the chapters have the number in a heart which is really cute. This is a UK book so I got the whole experience including the spelling they do across the pond. Where is this pond? Anyhoo I'm not sure if this book would appeal to everyone especially since British English and American English can sometimes seem like two different languages. They could have defined the terms that some people might not understand.
I have to admit that I was a bit confused at the beginning because it starts off with Delilah being on vacation or as you Brits say on holiday kissing a guy only to be at home all of a sudden. It was just a bit jarring to me. Maybe it was just me. Also the school system over there confuses me. The characters are sixteen so they are in the tenth grade but over there they refer to it as college. I think they call college university. I'm pretty sure one of the British soaps I watch have actually said high school. Well that isn't really important.
It is a cute story even though it can be confusing. The bit about Aphrodite's kiss seemed to be thrown in there and mentioned every once in a while to remind you. I think it would have been better if that part was just left out and it focused on the friendship between Delilah and Tabby. The title just doesn't seem to fit because I felt the best part of the story didn't revolve around this kiss that gets passed from person to person. It would be more enjoyable without that. The part about zombies was really interesting and this book had some cute moments. I also think people might be turned off with all those weird nicknames.
