Where in the World Is Sabrina Spellman

Blurb

Beauty-sleep blunder
When Sabrina learns that there is no coffee strong enough -- not even her aunt Hilda's -- to keep her awake the night before exams, she gives herself a magical energy boost. Sabrina even remembers to check the spell's fine print, and she's positive there are no adverse side effects for the spell caster.
But when Sabrina goes to school the next day, things are definitely not right. Sabrina's wide-awake, but everyone else is falling asleep...and won't wake up! Sabrina discovers the glitch in her spell, but to make everything right she's got to go on the scavenger hunt of a lifetime.
