Missing Angel Juan by Francesca Lia Block

Lonely City

A tangly-haired, purple-eyed girl named Witch Baby lives in glitzy L.A. She loves a guy named Angel Juan. When he leaves for New York she knows she must find him.

Looking For Love

So she heads for the city of glittery buildings and garbage and Chinese food and drug dealers and subways and kids playing hip-hopscotch.

Finding Trouble

Her clues are an empty tree house in the park, a postcard on the street, a mannequin in a diner. Angel Juan is in danger, and only Witch Baby's heart-magic can make him safe.

When Angel Juan leaves L. A.—and Witch Baby—to play his music and find himself in New York, Witch Baby, wild and restless without him, follows. The story that ensues "is an engagingly eccentric mix of fantasy and reality, enhanced—this time—by mystery and suspense. It is also magical, moving and mischievous, and—literally—marvelous."—SLJ.
