SOLVED. Mystery novel: About a boy and a girl who work together to uncover the secret of heat waves in their little town. [s]

[Disuja]

So the book is about a boy and a girl who wake up besides each other one morning and cannot remember anything at all. So when they start discovering themselves all over again they start looking for the reason people immediately faint when anything bad happens to them or they feel sad and wake up after few moments without any bad memory that happened a moment before. They call it heat waves in the book.

I read this book around last year from a library but can’t remember the name now when I want to re-read it.

For what age reader?
How old are the characters?
Cover?
Author's gender?

[Disuja]

Teens could be the possible readers and the main characters are themselves in high school. And I don’t remember anything regarding the author or the cover. The female character is very popular and the male is considered a freak.
