The Shadowshaper Cypher: Books 1-3 by Daniel José Older (Ex-Library HC/DJ)
With the help of a fellow artist named Robbie, Sierra discovers shadowshaping, a thrilling magic that infuses ancestral spirits into paintings, music, and stories. But someone is killing the shadowshapers one by one -- and the killer believes Sierra is hiding their greatest secret. Now she must unravel her family's past, take down the killer in the present, and save the future of shadowshaping for generations to come.
Full of a joyful, defiant spirit and writing as luscious as a Brooklyn summer night, Shadowshaper introduces a heroine and magic unlike anything else in fantasy fiction, and marks the YA debut of a bold new voice.
