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 her 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.
