Katy Birchall is a British author of teen/YA comedy and adult romantic comedies, and she also co-writes several middle-grade series.
Some of her books are true standalones, but her teen and children’s fiction is often series-based, where reading out of order can spoil relationship progress, running jokes, and “who knows what” reveals.

FAQs
Are Katy Birchall’s adult novels connected to her teen series?
No. The adult romantic comedies are designed to stand alone and don’t rely on her teen/children’s continuity.
Why do some It Girl titles look “different” depending on country?
Some editions emphasize Superstar Geek branding, while others foreground The It Girl series name. Matching by series number is the safest approach.
Do I need to read the co-authored books to understand her solo novels?
No. Treat co-authored projects as a separate shelf: they have their own continuity, tone, and intended readership.
