4A determined young girl joins forces with an adventure-loving street boy to save her father's life in this "thoroughly entertaining" (Kirkus Reviews) magical murder mystery.

In the spell-powered city of Tarreton, the wealthy have all the magic they desire while the working class can barely afford a simple spell to heat their homes. Twelve-year-old Isaveth is poor, but she's also brave, loyal, and zealous in the pursuit of justice--which is lucky, because her father has just been wrongfully arrested for murder.

Isaveth is determined to prove his innocence. Quiz, the eccentric, eyepatch-wearing street boy who befriends her, swears he can't resist a good mystery. Together they set out to solve the magical murder of one of Tarreton's most influential citizens and save Isaveth's beloved Papa from execution. But is Quiz truly helping Isaveth out of friendship, or does he have hidden motives of his own?
