Chloe Walsh continuously brakes the rules of romance books and makes it work, she is one of the only authors that can write a love interest who is a complete man-whore and make it work, as well as the only author to write the main couple not ending up together and it works, Yes I know there is a sequle but it could easily be a standalone.

At the same time there are so many endings that could work that you don't know what is going to happen, Tegan could have gone home over valentines day and Noah could have died, Noah could have ran away with Tegan, Tegan could have never forgiven him for his step-sisters actions.
