Thirteen-year-old Ava Bigtree has lived her entire life at Swamplandia!, her family’s island home and gator-wrestling theme park in the Florida Everglades. But when illness fells Ava’s mother, the park’s indomitable headliner, the family is plunged into chaos; her father withdraws, her sister falls in love with a spooky character known as the Dredgeman, and her brilliant big brother, Kiwi, defects to a rival park called The World of Darkness.

As Ava sets out on a mission through the magical swamps to save them all, we are drawn into a lush and bravely imagined debut that takes us to the shimmering edge of reality.

This was the first time I’ve read Karen Russell’s work, and I was dazzled. It’s very rare, among the tonnage of manuscripts and galleys that land upon one’s desk, to come across a young novelist so inventive and versatile, yet so thoroughly in control. Also, I’m a sucker for any plot line that features man-eating reptiles.

Swamplandia! is the story of Ava Bigtree, a 12-year-old alligator wrestler who embarks on an improbable journey through the mangrove wilderness of southwest Florida in search of a lost sister. Young Osceola has run off with a ghost-figure named Louis Thanksgiving, and only Ava knows where to look for them, dreading what she might find. Passages of this fine novel call to mind Conrad, Garcia Marquez and even – for those who have kids – Judy Blume. There’s not a forgettable character in the cast, from Ava’s flamboyant father, Chief Bigtree, who runs the family’s failing tourist trap, to the bedraggled and cryptic Bird Man, who guides Ava on her harrowing trip.

Having spent many days in the Ten Thousand Islands, I was enchanted by Russell’s dream-like descriptions of the tangled and serpentine creeks, the funky and exotic flora, the long stare of circling buzzards. Her prose is both shimmering and stark: “A huge hole in the middle of the ceiling opened onto a clear night sky; it looked as if some great predator had peeled the thatched roof back, sniffed once and lost interest.”

Or the way she describes a “cauldron” of moths with “sapphire-tipped wings, a sky-flood of them…They had fixed wings like sharp little bones, these moths, and it was astonishingly sad when you accidentally killed one.”

I can’t recall the last time I came across a character who shines as brightly as Ava, or a first novel that made such a rich and lasting impression.
