The Bigtree alligator wrestling dynasty is in decline and Swamplandia!, their island home in the Florida Everglades and gator-wrestling theme park, is swiftly being encroached upon by a sophisticated competitor known as The World of Darkness. Ava, a resourceful but terrified twelve year old, must manage seventy gators and the vast, inscrutable landscape of her own grief. Her mother, Swamplandia!'s legendary and beautiful star attraction, has just died; her sister is having an affair with a ghost called the Dredgeman; her Grandpa Sawtooth has been sent to the mainland to an old folk's home; her brother has secretly defected to The World of Darkness in a last-ditch effort to keep the family afloat; and her father, the Chief, is AWOL. To save them, Ava must journey on her own to a perilous part of the swamp called the Underworld, a harrowing odyssey from which she emerges a true heroine.

Swamplandia! is a dark and mythic story, bursting with energy and an unstoppable inventiveness, by a writer with an astonishingly original and exuberant imagination.
