Cody's not just growing up... he's growing fins!

A teen learns that his birth mother is a mermaid after he begins to grow fins and slimy scales on his thirteenth birthday.
In The Thirteenth Year, consciousness is carried by monsters and creatures — a plane of “mermaid adolescence”. The story fights on E8/E9 of the E0–E14 reality ladder, compressing identity, otherness, family, transformation.
