The Illustrated Eric by Terry Pratchett

A hapless, myth-themed comic tale in which a teenage aspiring demonologist mistakenly summons a timid, luckless wizard and coerces him into granting three wishes; the resulting misadventures—ranging from literal-minded wish outcomes to chaotic jaunts through infernal and extraordinary realms—turn into a sharp, playful satire of wish-fulfillment, heroism, and bureaucratic absurdity, driven by irreverent humor and brisk, inventive plotting.
