From Newbery Honoree Carl Hiaasen comes this New York Times bestseller in
which an eccentric eco-avenger, a stuffed rat named Chelsea, a wannabe Texas
oilman, and an angry panther can't stop two kids on a mission to find their
missing teacher!

When Mrs Starch, the most feared biology teacher in Florida, goes missing
during a school trip to the Black Vine Swamp, her class is secretly relieved.

The school principal tries to cover it up as a 'family emergency', but Nick
and Marta just aren't convinced. They think it's much more likely to have
something to do with Smoke, the local troublemaker - whose run-ins with Mrs
Starch are infamous - and decide to do some investigating of their own.

But there's more going on in Black Vine Swamp than either one of them could
guess. And Nick and Marta must see off an eccentric eco-avenger, a stuffed rat
named Chelsea, a crooked oil prospector, a singing substitute teacher, and an
angry Florida panther before they really begin to see the big picture.
