Two months after the events of Frozen 2, the Arendelle sisters are still adjusting to their new roles. Elsa rules over the Enchanted Forest but admits, “even now that I’ve taken my place among the spirits, magic isn’t always easy.”  Meanwhile, Anna is newly engaged and new queen of Arendelle. While in the midst of planning for the annual Polar Night’s Festival, Anna takes a break to visit her sister alongside Kristoff, Olaf, and Sven. Around a campfire, Kristoff recalls the legend of a different pair of royal sisters, how one drowned the other in a jealous rage. The murdered sister arose as a zombified creature—a draugr—a “‘soulless monster ready to seek revenge against those who did it wrong.’”

After Kristoff finishes the story, a mysterious storm blows in, and when he and Anna return to Arendelle the next day, something is amiss. Storms keep coming, the sky grows darker and darker, and everyone seems to be losing their memories. It seems the draugr from the story is real and after them. Anna and Elsa must embark on a quest to figure out how to stop the creature before it’s too late.

Disney Frozen Polar Nights is told from the alternating third-person perspectives of Elsa (written by Mancusi) and Anna (written by Calonita). The two authors seamlessly blend the chapters and the story flows well. The reader gets a glimpse into the thoughts and feelings of both sisters and is able to have a better understanding of their relationship with each other as a result. Through the characters’ actions, the franchise’s theme of sisterhood and the importance of family are brightly showcased.

Anna, Elsa, and the other characters stay true to how they were portrayed in the films. The bond between the sisters is well illustrated, and their dynamic is charming, with Anna being more impulsive and Elsa being more grounded. Because of their differences, they balance each other out and bring out the best in each other. Anna’s romance with Kristoff is also very sweet, and it’s charming to watch them interact because they show how much they care about each other.

The plot revolves around Anna and Elsa figuring out the truth of what happened between the sisters from Kristoff’s story. It is a bit predictable that the circumstances around the death of the younger sister differ dramatically from the story that spread, and that this misinformation is the primary cause of the spiritual unrest. However, the journey is still enjoyable and is certain to captivate the target demographic.

Fans of Frozen will be swept up in this story that so vividly captures the Frozen world and characters. Disney Frozen Polar Night is a dramatic tale, but characters like Olaf provide some humor along the way to balance things out. The spooky story contains some imagery and tense moments that might be scary for certain readers. However, readers who appreciate monsters and mystery will enjoy the familiar characters and simple plot. Readers who are looking for kid-friendly ghost stories should add The Trail of the Ghost Bunny by Linda Joy Singleton to their reading list. Readers who love fairytale-inspired stories can jump into other fairytales by reading the Whatever After Series by Sarah Mlynowski.

Sexual Content

  • Anna and Kristoff kiss multiple times. The kisses are not described in detail. For example, the most detailed description depicts Kristoff “kissing her deeply” during an emotional reunion between the two at the end.


  • Kristoff tells a legend of sisters Inger and Sissel. In a jealous rage, Inger “snuck behind [Sissel] and shoved her in [a river].” Inger watches as Sissel went over a waterfall and drowned.
  • While running from the draugr, Anna hits her head on a rock and injures her ankle. Elsa notes the “blood crusting in her sister’s hair.”
  • Elsa nearly drowns after falling into a river. As the current drags Elsa, she was “gulping river water too fast, choking and sputtering as she [tries] to find the river’s bottom . . . her feet only [kick] uselessly.” Anna saves her.
  • Elsa and Anna witness a vision of Sissel’s drowning. The vision reveals that the drowning was in fact accidental. Sissel tried to hold onto a branch by the riverbank for support but “the branch broke free. Sissel’s body was tossed like a rag doll over the [waterfall]. Inger screamed in agony, collapsing to the ground.”
  • A pirate ship shoots cannonballs at a ship that Anna and Elsa are on. Elsa needs to get to the ship to deliver a message. She rides there on the Nokk (a horse-shaped water spirit) while fighting the onslaught with her ice powers. “The cannonballs hit the ice in front of them . . . shattering [them] into a thousand pieces.” Elsa manages to get to the ship unscathed and stop the attack. The attack is described over four pages.
  • Plagued by memory loss, an Arendellian general named Mattias draws his sword and attempts to attack Sissel (still in the form of a draugr). He says, “I will slash you down where you stand.” As he charges Sissel, Elsa shoots an ice wall in front of him. He bounces “off the ice, falling backward and landing hard on the ground,” stopping from harming Sissel. He is not seriously injured.

Drugs and Alcohol

  • None


  • None


  • Elsa lives in the Enchanted Forest, home to the wind, fire, water, and air spirits who appear at certain points throughout the story. The fire spirit Bruni, for example, takes the form of a salamander that can catch fire at will.
  • The plot revolves around Sissel’s spirit coming back as a vengeful creature known as a draugr. Draugrs are “creatures of old folklore, and they supposedly cause terrible storms when they show up.” The draugr “haunts Arendelle and [steals] memories to try and make people stop thinking [her sister] murdered her.”
  • The group hears mysterious moaning in the night and when they go to investigate, their tent is knocked down by an apparent supernatural force.
  • The draugr appears to Anna and Elsa. It is described as “clearly human shaped . . . [with] blackened skin, misshapen bones . . . and green slime oozing from its pores.” The creature calls for its sister, and Anna and Elsa attempt to fight it off before running. It eventually vanishes but appears to the sisters a couple more times. It never harms them.
  • Eventually, Anna learns that the draugr isn’t really a ghost, but rather a “reanimated, decayed corpse… [that] didn’t receive a proper burial.”
