About

two teenagers—Mary Reynolds and Charlie Young—have no idea that their ordinary high-school lives are connected to an ancient magical world hidden beneath their town. Charlie, who recently moved to Lakeville from Montana, discovers a mysterious blue dragonfly necklace buried beneath the town. The necklace chooses him as a Trollhunter, giving him access to magic and abilities that he never knew he possessed. Meanwhile, Mary has already found a strange purple butterfly necklace. She originally wears it simply because she thinks it’s pretty and has no idea that it is connected to Charlie—or that it has chosen her as a second Trollhunter. The two necklaces are part of an ancient legend: a Dragonfly and Butterfly Trollhunter are destined to fight alongside one another. Their magic isn’t actually created by the necklaces. Mary and Charlie were born with magical abilities; the necklaces simply unlock that power, while magical stones they collect can give them additional abilities such as super speed, flight, and shifting. As strange creatures begin appearing around Lakeville, Charlie realizes something supernatural is happening. Eventually, he discovers that Mary is connected to it too. What begins as two teenagers trying to understand their strange necklaces becomes a much bigger responsibility as they are pulled into Trollmarket, a hidden civilization beneath their town populated by trolls and other magical creatures. Mary initially tells her best friend Avery, who has known her since fourth grade, about everything. Lincoln eventually discovers the secret as well, becoming part of their growing group. Their friends slowly become entangled in the dangerous and sometimes ridiculous world of trollhunting. Between fighting monsters, sneaking around school, dealing with teachers, keeping their identities secret, and attempting to maintain normal teenage lives, Mary and Charlie struggle to balance being students with being heroes.
