I think I made my feelings about the book very clear when I started the review. I loved it. I loved the diverse representation and that there wasn't a forced romance. And more than everything, I loved the character arcs and how strongly they were developed.
The theme of mysterious history of Frances and Carys and the mysterious present between Daniel and Aled's friendship kept me hooked. While the writing quintessentially represents a millennial teenager's POV, it was not angst-y and irksome, even when it was bit longer.
