Waiting on Wednesday: Rampant by Diana Peterfreund

The sparkly, innocent creatures of lore are a myth. Real unicorns are venomous, man-eating monsters with huge fangs and razor-sharp horns. And they can only be killed by virgin descendants of Alexander the Great. 

Fortunately, unicorns have been extinct for a hundred and fifty years.

Or not.

Astrid Llewelyn has always scoffed at her eccentric mother’s stories about killer unicorns. But when one of the monsters attacks her boyfriend in the woods — thereby ruining any chance of him taking her to prom — Astrid learns that unicorns are real and dangerous, and she has a family legacy to uphold. Her mother packs her off to Rome to train as a unicorn hunter at the ancient cloisters the hunters have used for centuries.

However, at the cloisters, all is not what it seems. Outside, the unicorns wait to attack. And within, Astrid faces other, unexpected threats: from crumbling, bone-covered walls that vibrate with a terrible power to the hidden agendas of her fellow hunters to — perhaps most dangerously of all — her growing attraction to a handsome art student… and a relationship that could jeopardize everything.

In other words, unicorns are really awesome. BAMF unicorns? I might as well join Peterfreund’s fan club.
