Emily Rath's North Is the Night is a mesmerizing journey into a world where Finnish folklore and mythology intertwine with the lives of two courageous young women, Siiri and Aina. This novel, the first in a duology, offers a rich tapestry of themes, character development, and a narrative that is as enchanting as it is haunting.

At its core, North Is the Night is a tale of love, loyalty, and defiance against both mortal and divine forces. Set against the backdrop of the Finnish wilderness, Rath crafts a world that is both beautiful and perilous. The encroaching threat of land-hungry Swedes and the zealous Christian priest serve as a metaphor for the clash between tradition and change, a theme that resonates deeply throughout the narrative. The fading summer light not only signals the end of a season but also the impending darkness that Siiri and Aina must navigate, both literally and metaphorically.

The character development in this novel is nothing short of remarkable. Siiri, with her fierce determination and unwavering loyalty, embodies the spirit of a warrior. Her vow to protect Aina from danger is not just a promise but a testament to the depth of her love and commitment. Rath skillfully portrays Siiri's internal struggle as she grapples with the limitations of her power against the supernatural forces that threaten her world. Her journey north to seek the legendary shaman is a quest not just for Aina's salvation but also for her own understanding of courage and sacrifice.

Aina, on the other hand, is a character of quiet strength and resilience. Her capture by the death goddess and subsequent torment in Tuonela, the mythical underworld, is a harrowing experience that tests her spirit. Yet, it is in this dark realm that Aina's character truly shines. Armed with compassion and cleverness, she navigates the treacherous landscape of the underworld, uncovering the truth behind her capture. The revelation that the king of the underworld has plans for her adds a layer of complexity to her character, forcing her to confront her own desires and fears. Aina's journey is one of self-discovery, and her ability to bargain her heart in the face of overwhelming odds is a testament to her inner strength.

The relationship between Siiri and Aina is the emotional heart of the novel. Rath portrays their bond with sensitivity and depth, capturing the nuances of a friendship that transcends the ordinary. Their love is a powerful force that drives the narrative forward, and their individual journeys are inextricably linked. The novel's exploration of love in its various forms—romantic, platonic, and familial—is both poignant and profound, adding layers of emotional complexity to the story.

Rath's writing is both lyrical and evocative, capturing the beauty and brutality of the Finnish wilderness with equal skill. Her descriptions of the dark forests, the mythical creatures that inhabit them, and the chilling atmosphere of Tuonela are vivid and immersive. The novel's pacing is well-balanced, with moments of intense action interspersed with quieter, introspective scenes that allow for character development and thematic exploration.

In terms of its overall impact, North Is the Night is a compelling addition to the fantasy genre. Its blend of Finnish folklore and mythology with a narrative centered on strong female protagonists sets it apart from other works in the genre. The novel's themes of defiance, love, and the struggle between tradition and change are universal, resonating with readers on multiple levels.

Comparatively, Rath's work can be likened to the mythological depth found in Madeline Miller's Circe or the atmospheric world-building of Naomi Novik's Uprooted. Like these authors, Rath has a talent for weaving myth and reality into a cohesive and captivating narrative. However, North Is the Night stands out for its unique cultural perspective and its focus on the power of female friendship and love.

In conclusion, Emily Rath's North Is the Night is a beautifully crafted tale that captivates the reader from beginning to end. Its rich themes, well-developed characters, and immersive world-building make it a must-read for fans of fantasy and folklore. The novel not only entertains but also invites readers to reflect on the nature of love, loyalty, and the courage to defy the odds. As the first in a duology, it sets the stage for what promises to be an equally enthralling continuation of Siiri and Aina's story.
