Rent in New Metta is through the cavern ceiling. When Granu barely survives her first gig teaching students who attempt to fillet her for lunch, the baby-eating troll ends up unemployed and facing eviction. Granu's only prospect for income is grueling work in the tar pits. That is, until her playboy best friend devises a perfect, if suicidal, scheme-a heist!

The Covered Bridge, the largest source of income for the city, has New Metta well under hoof. In a week, TCB Corporation pulls in enough cash to buy a small country. It's the ideal target, but security is top-notch. Granu needs three things to survive this heist: a crew of specialists, impenetrable sun protection, and gallons of grog.

There's just one thing Granu doesn't plan for-those damn meddling billy goats.
