Jim Butcher's The Dresden Files: Welcome to the Jungle #3 (of 4)

In the city of Chicago, wizard-for-hire Harry Dresden switches from hunter to hunted as he continues following the trail of a supernatural killer haunting the Lincoln Park Zoo. The stakes increase and the tension ratchets higher as monstrous assassins and dark magic claim more innocent lives. Dresden must survive the killer's onslaught and turn the tables, and fast, before the body count rises - and before the killer can reach her ultimate goal!
