Alex is a bruja and the most powerful witch in her family. But she's hated magic ever since it made her father disappear into thin air. When a curse she performs to rid herself of magic backfires and her family vanishes, she must travel to Los Lagos, a land in-between as dark as Limbo and as strange as Wonderland, to get her family back.

When Julia finds a slur about her best friend scrawled across the back of the Kingston School for the Deaf, she covers it up with a beautiful (albeit illegal) graffiti mural. Her supposed best friend snitches, the principal expels her, and her two mothers set Julia up with a one-way ticket to a "mainstream" school in the suburbs, where she's treated like an outcast as the only deaf student. The last thing she has left is her art, and not even Banksy himself could convince her to give that up. Out in the 'burbs, Julia paints anywhere she can, eager to claim some turf of her own. But Julia soon learns that she might not be the only vandal in town. Someone is adding to her tags, making them better, showing off--and showing Julia up in the process. She expected her art might get painted over by cops. But she never imagined getting dragged into a full-blown graffiti war.

When the murals painted on the walls of her Brooklyn neighborhood start to change and fade in front of her, Sierra Santiago realizes that something strange is going on--then she discovers her Puerto Rican family are shadowshapers and finds herself in a battle with an evil anthropologist for the lives of her family and friends.
