The sunken tower

"Dig is having a very bad day. His bag is broken, he can't catch a break at the local market, and just when things are looking up, he's kidnapped by a couple of Blood Cultists and taken to the underground city that serves as their base, where he'll make a tasty human sacrifice for an unspeakably horrible monster. Thrown into a dungeon, he has no idea how to escape -- or if anyone will care if he does. But his new cellmates, Iana and Crina are ecstatic about Dig's appearance. He's a wizard which means he knows magic, which means he can help them all out of this terrible sunken city for good! If Iana can get her hands on a sword, and Crina can remember the way to the giant tower that leads to the surface, then everything will go smoothly"--Back cover.
