Emily Tucker is the sixteen-year-old sister of Grady Tucker. The siblings are forced to move to Fever Swamp in Florida because their father, Dr. Tucker, is a scientist attempting to study the effects of a Floridian swamp's environment on a group of deer. Dr. Tucker keeps the animals in a pen outside of his family's new house.
The kids eventually meet several residents who live near them: a crazy looking hermit, a local boy named Will Blake, and a weird local girl named Cassie O'Rourke. The Tucker family also finds a dog in the woods, which they keep and name Wolf. Peculiarly, animals in the area begin dying, and the family doesn't know who or what to blame. Local legends suggest that a werewolf might be responsible, and this is ultimately revealed to be true.
While Grady ends up meeting the werewolf of Fever Swamp, Emily does not, and her life is left relatively unchanged by the end of the book.
Emily is less adventurous — and more indifferent — than her brother. In Grady's opinion, she can be a braggart, often acting as if she is intellectually superior.
