3,5 stars, actually
I'm not very fond of teenage drama and I don't really like love drama with famous people bc it reminds me of a fanfiction with 1D, 5SOS, JB ect. but I liked the book and heroes, it's story is well...well, it's really well written and it is a light read, especially when you're reading a book like A Game of Thrones.
Honestly, Joss Stirling's books are not as great as I'd want them to be, but they are good enough and I've always liked them.
