An unputdownable murder mystery from an exciting new voice in YA fiction.
We notice when they wear each other's clothes, or tie a new stupid bit of string around their wrist, or trim their hair. We knew that Frankie and Jack were made for each other years before they were finally allowed to admit it. We know these boys. We can work out their behaviour - most of the time predict their behaviour - because we've spent so long analysing every move they make.
And we know enough about Frankie Williams to prove he didn't do it.
Harri and her best friends worship Half Light - an internationally famous boyband. When frontman Frankie is arrested on suspicion of murdering his oldest friend Evan, Harri feels like her world's about to fall apart. But quickly she realises that she - and all the other Half Light superfans out there - know and understand much more about these boys than any detective ever could.
Now she's rallying a fangirl army to prove Frankie's innocence - and to show the world that you should never underestimate a teenage girl with a passion...
