CASS BIEHN

Cass Biehn (they/them) writes messy queer characters in messier situations—and always with angsty kissing.

They hold a Master of Library Science from Aberystwyth University in Wales and currently live in the Utah desert, where they split their time between cosplaying and wrangling their dogs.

Cass' debut novel, VESUVIUS, will release June 3, 2025 from Peachtree Teen in the US and June 5, 2025 from Atom Books/Little, Brown in the UK. Their second novel, THOUGH THIS BE MADNESS, is slated for release in 2027.

Cass is represented by Annalise Errico of Ladderbird Literary.

VESUVIUS


They Both Die at the End meets The Song of Achilles in VESUVIUS, a queer YA Historical Fantasy.

Set in Pompeii days before the eruption of Mount Vesuvius, two boys—Felix and Loren—must grapple with their closely-guarded secrets and untangle their fates to make it out of the burning city alive.


This is a meet-cute with an explosive fallout.


Coming in 2027.

On submission.
