Written by Polly Horvath in 1999, The Trolls is a child's novel based in the present time with stories told by Aunt Sally dating back twenty or so years ago. The Trolls was a National Book Award finalist, and is a Boston Globe-Horn Book Award Honor book.

The books starts out with Mr. and Mrs. Anderson, parents of Melissa, Amanda and Pee Wee, having planned a trip to Paris, but the babysitter cancels last minute due to a development of bubonic plague requiring them to resort to the only available person left: Aunt Sally. Once Aunt Sally arrives and the children’s parents leave they are treated to many of Aunt Sally’s stories revolving around her life in Vancouver with her eccentric family.

!!The Trolls Contains examples of:
* AnAesop: While little ones crop up here and there in Aunt Sally's stories, perhaps the biggest message is also, interestingly, the stealthiest one: be nice to your siblings.
** [[spoiler: [[FantasticAesop Don't feed your siblings to trolls]]]]
** PlayedForLaughs with the story of John, Great-Uncle Louis, and the fiddleheads. The doctor who patches the two up at the end concludes that the moral of the story is [[FamilyUnfriendlyAesop that it's best not to do things for your health]].
* AuthorAppeal: Polly Horvath lives in Vancouver and milks it for all it's worth.
* BlackMagic: SubvertedTrope. The Wiccan's only preform 'friendly' spells.
* BlackComedy: The story about Sally, John, and Edward accompanying Mad Maud hunting. Maud begins to act increasingly creepy and strange, telling terrifying stories about people getting killed by cougars. She then starts shooting small woodland creatures, apparently thinking they're cougars, and finally shoots ''[[CrossesTheLineTwice the postman]]''. [[RefugeInAudacity And seems genuinely unaware that she's the reason he's bleeding]]. Fortunately he's more shaken than injured.
* CanadaEh: Aunt Sally both pokes fun at and provides true facts about Vancouver.
* [[CoolUncle Cool Aunt]]: Aunt Sally is for the kids.
** Great-Uncle Louis thinks he's a CoolUncle, but only Robbie really thinks he is.
** Hattie is viewed as something like this by Sally and her siblings, after she starts recovering from her past traumas and tells Great-Uncle Louis just what she thinks of him (namely that he's an old windbag and "less of a man and more of an excuse to hold up a mustache").
* CoolOldLady: Aunt Sally, John, and Edward think Mad Maud is this at first, impressed by her record of cougar hunting. They quickly change their minds when they realize just how crazy she is.
* CloudCuckooLander: Mad Maud.
* DysfunctionalFamily: Aunt Sally's generation has become very dysfunctional after [[spoiler: she and her siblings ditch Robbie on the beach with 'the trolls'.]]
* EccentricMentor: Aunt Sally, under the guise of telling the kids interesting stories, is definitely still teaching the children a thing or two.
* EccentricTownsfolk: The residence of Aunt Sally's hometown in Vancouver.
* ExactlyWhatItSaysOnTheTin: Fat-Little-Mean-Girl is in fact a fat, little, mean girl.
* FormallyNamedPet: Mrs. Gunderson.
** And the new Mrs. Gunderson.
* LargeHam: Definitely Great-Uncle Louis, who came for two weeks and stayed for six years.
* MaybeMagicMaybeMundane: Did the potion the Wiccans gave Aunt Sally and her sibling really work, or did Fat-Little-Mean-Girl just react to drinking something... weird.
** [[spoiler: Were there really Trolls that lived out in the caves on the beach?]]
* MamaBear: In one of the stories Mad Maud told, a mother is killed saving her child from a cougar.

* OverusedRunningGag: Great-Uncle Louis, who came for two weeks and stayed for six years.
* PapaWolf: Aunt Sally tells the kids how their grandfather was one of the quietest, nicest guys you could ever meet. When he learns that a clam bit the end of one of his kid's fingers off though, he goes after it with a shot gun.
* ReformedButRejected: Aunt Sally to her brother (and the kids' dad) Robbie.
* TheThingThatWouldNotLeave: Great-Uncle Louis, who came for two weeks and stayed for six years.
