Shadowshaper is a 2015 American urban fantasy young adult novel written by Daniel Jose Older. It is the first in the Shadowshaper Cypher series. It follows Sierra Santiago, an Afro-Boricua teenager living in Brooklyn. In the book it is revealed that she is the granddaughter of a "shadowshaper", or a person who infuses art with ancestral spirits. As forces of gentrification invade their community and a mysterious being who appropriates their magic begins to hunt the aging shadowshapers, Sierra must learn about her artistic and spiritual heritage to foil the killer. Four sequels have followed: "Ghostgirl in the Corner" (a novella, 2016), "Dead Light March" (a novella, 2017), Shadowhouse Fall (novel, 2017) and Shadowshaper Legacy (novel, 2020).
