Eliza Kissane: The Blind Twin Who Sees Beneath the Waves

Overview

Eliza Kissane is one of two Irish convict sisters transported aboard the Naiad in 1800. Blind from birth, she possesses an uncanny ability to navigate the dark and a fierce, almost supernatural connection to water—a connection that becomes a source of both danger and power. In Emilia Hart’s The Sirens, Eliza functions as Mary’s emotional anchor and, eventually, a catalyst for the sisters’ shared transformation. Her arc from a rebellious seeker of their drowned mother to a protector of the other convict women traces the novel’s central themes of sisterhood, trauma, and the reclamation of agency.

Plot Role

Eliza’s role unfolds primarily through Mary’s memories and modern descendant Lucy’s dreams. She is the catalyst for the sisters’ arrest: on Samhain night, when Mary is assaulted by Byrne, Eliza strikes him with a rock, an act that leads to their conviction for assault and transportation. During the voyage, Eliza’s deepening transformation—her skin becoming scaled, her toes webbing—mirrors Mary’s and foreshadows the women’s eventual metamorphosis. When the Naiad founders in a storm, Eliza helps Mary and fellow convicts like Bridie and Sarah escape the sinking hold, guiding them through the dark bilge as only she can. In the novel’s resolution (as Lucy and Jess conclude in Chapter 48), Eliza and Mary are presumed lost to the sea—yet their spirits remain, no longer needing to haunt their descendants because the sisters have each other and the ocean.

Motivations and Traits Shown Through Actions

Eliza’s core motivation is reunion with her mother—a woman who, Mary believes, drowned when the girls were young. From the night she first leads Mary to the stream, searching for the mythical tír fo thuinn (the land beneath the waves), Eliza is driven by a longing to find Mam. This pursuit is both spiritual and physical: she defies her father’s warnings about water’s danger, trusting that the sea will protect rather than harm her.

Her blindness is not a limitation but an asset. In the darkness of the ship’s hold, she moves “sure-footed in the dark,” humming and dancing ahead while Mary stumbles. She has “an ear for lies” and can detect falseness in her sister’s voice. During the storm, it is Eliza who remains calm, whispering stories and soothing Mary to sleep. When violence erupts—Byrne’s assault—she acts without hesitation, striking him with a rock. Later, she insists that the water made her strong, reframing vulnerability as power.

Chronological Arc

Relationships

• Mary (twin sister): Eliza’s most vital bond. She calls Mary mo dheirfiúr (my sister) and trusts her to describe the world. Their connection is psychic: Mary feels Eliza’s heart “thrum in time with hers.” Eliza’s actions (going to the stream, attacking Byrne) are always intertwined with Mary’s safety.
• Da (father): Eliza loves him but defies his prohibitions on water. She believes the sea is her birthright, not a threat—a stance that creates a quiet rift.
• Mam (the drowned mother): An absent figure whom Eliza idealizes. She seeks Mam through the tír fo thuinn myth and, later, through her own transformation.
• Bridie, Sarah, and other convicts: Eliza shares food and solidarity; she participates in the collective escape, using her blindness as an advantage in the dark hold.

Key Decisions and Consequences

1. Going to the stream on Samhain → Leads to Byrne’s assault and the sisters’ transportation. This decision sets the entire plot in motion.
2. Striking Byrne with a rock → Saves Mary but results in their arrest. Eliza never regrets this act; she later tells Mary the water made her strong.
3. Accepting the transformation → Unlike Mary, who fears the changes, Eliza embraces her scaling skin and webbed toes. She interprets them as a gift from the sea that “protected me.”
4. Helping the women escape the sinking ship → Ensures that some of the convicts (e.g., Bridie, Sarah, Annie) survive the wreck. Eliza’s guidance through the darkened hold is a direct application of her blindness.

Theme and Symbol Connections

Sisterhood and Family Bonds

Eliza’s devotion to Mary is the emotional core of the narrative. Their twin bond—telepathic, protective, unconditional—echoes in modern sisters Jess and Lucy. The sisterhood and family bonds theme page explores how the Kissane sisters’ loyalty transcends time and death.

Identity and Self-Discovery

Eliza’s blindness forces her to construct identity through sound, smell, and touch—and she discovers her true self in the water. Her desire to “find Mam” is a search for origins; the identity and self-discovery theme page examines how the characters reclaim their histories.

Trauma and Memory

The assault by Byrne, the loss of home, and the terror of transportation are encoded in Eliza’s body. She channels trauma into action and transformation. The trauma and memory theme page discusses how past violence shapes present bodies.

Colonization and Oppression

Eliza and Mary are victims of British colonial rule—transported for defending themselves against a male attacker. The Naiad voyage represents the brutality of the convict system. See the colonization and oppression theme page for historical context.

Transformation and Monstrosity

Eliza’s physical metamorphosis is presented not as horror but as liberation. The word “monstrosity” is subverted: the women become sirens, not victims. The transformation and monstrosity theme page analyzes how the novel redefines the monstrous.

Frequently Asked Questions

1. Does Eliza survive the shipwreck? The novel leaves her fate ambiguous. In Chapter 48, Lucy and Jess believe Eliza and Mary “no longer need” to appear to them because the sisters now have the sea and each other. This suggests they either drowned and became spirits or fully transformed into the mermaid-like beings of local legend. No explicit death is shown; they simply pass out of the historical record.

2. Why does Eliza go to the stream at night? She is searching for the tír fo thuinn—the underwater land where she believes her mother went. Eliza has never fully accepted her mother’s death; the stream is a portal to that other world. Mary later describes this night as the moment “the water that makes us strong” began calling to Eliza.

3. How does Eliza’s blindness serve her? It gives her an advantage in darkness, on the ship’s lower deck, and during the storm. She can move without sight, hear lies, and remain calm when others panic. The novel treats her blindness as a form of heightened perception rather than a disability.

4. What is Eliza’s role in the rescue of the other women? When the Naiad sinks, the hold is black and flooding. Eliza guides the women through the water, using her instinctive knowledge of the dark. She helps Bridie, Sarah, and young Annie reach safety; Mary describes feeling Eliza’s hand leading them toward the deck.

5. Does Eliza reconcile with Mary before the end? Yes. After the sisters argue about their mother and Mary feels guilt for their fate, Eliza reassures her during the storm. They hold hands and press close together. In their final shared moments on the ship, Eliza whispers the story of Mam to comfort Mary—a gesture that heals the rift between them.
