Swamplandia!

In the Florida Everglades, gator-park Swamplandia! is in trouble. Its star performer, the great beauty and champion alligator-wrestler Hilola Bigtree, has succumbed to cancer, and Ava, her resourceful but terrified 13-year-old daughter, is left in charge with her two siblings. But Ava's sister has embarked on a romantic relationship with a ghost, her brother has defected to a rival theme park, and her father is AWOL. And then a mysterious figure called Bird Man guides Ava into a perilous part of the swamp called the Underworld, promising he can save both her sister and the park...
Swamplandia! was longlisted for the 2011 Orange Prize and shortlisted for the 2012 Pulitzer Prize and 2013 IMPAC Dublin Literary Award.
