‘The Last Sunrise’s’ Chronic Illness Explained: Why Ry’s Tuberous Sclerosis Diagnosis in the Amazon Movie Hits so Close to Home

‘The Last Sunrise‘ has landed on Prime Video, and viewers are already asking exactly what kind of chronic illness the film’s heroine is living with. The romantic drama, based on the bestselling novel by Anna Todd, follows Oriah “Ry” Pera as she spends what she believes could be her final summer in Mallorca, and her health condition is not just a plot device but the emotional core of the entire story.

The movie stars Maia Reficco as Ry, a college student navigating a chronic illness during a summer trip with her mother, played by Eva Longoria as the pair escape to Mallorca together. As she falls for a local named Julián, played by Fernando Lindez, her worsening condition and her family’s hidden secrets threaten to unravel everything before summer’s end as her worsening condition and long-hidden family secrets threaten to unravel everything before the summer ends.

What Chronic Illness Does Ry Have in ‘The Last Sunrise’?

Ry’s specific diagnosis is tuberous sclerosis, a rare genetic disorder that causes noncancerous tumors to grow in various parts of the body, and the film also shows her dealing with epilepsy as a result of the condition as Todd tells the story of Oriah dealing with chronic health issues, including tuberous sclerosis and epilepsy.

The film adaptation, directed by Carlson Young, does not shy away from depicting how the disorder physically affects Ry’s daily life. One review noted that the novel handles the illness with unflinching honesty, describing Ry’s seizures and the exhaustion that follows them in a way meant to feel true to life rather than sanitized for drama as the novel handles tuberous sclerosis with sensitivity and research-backed accuracy, and her condition isn’t used merely for dramatic effect but shapes her worldview and choices.

Content advisory trackers for the source novel have also flagged the heavier material readers and viewers should expect going in, including chronic illness, terminal illness, grief, and mental health struggles woven throughout the story with graphic content warnings covering chronic illness, death, mental illness, sexual content, terminal illness, medical content, and grief.

Why Anna Todd Chose Tuberous Sclerosis for ‘The Last Sunrise’

The decision to give Ry this exact diagnosis was deeply personal for Todd, whose own son Asher lives with tuberous sclerosis complex, along with autism and epilepsy that frequently accompany the disorder. In interviews tied to the film’s release, Todd explained that writing Ry’s story became a way of processing her family’s own experience, describing the process as therapeutic even though it forced her to sit with emotions she had not fully unpacked since her son’s diagnosis.

Todd has said she wanted a story where a character managing a serious illness could still find joy, connection, and romance instead of following the familiar tragic arc so common in the genre. She pointed to a desire to move past the pattern of chronic illness stories always ending in sorrow, insisting that people living with these conditions deserve narratives with hope built in rather than only heartbreak.

Todd has also been candid that Ry’s version of the illness is intentionally less severe than what her own son experiences in real life, since she wanted to depict a realistic version of tuberous sclerosis without piling on every possible complication the disorder can cause. She has noted there are many different presentations of the condition, and that Ry’s fictional case was shaped to serve the story’s balance of realism and hope.

Beyond the writing itself, Todd took on a producer role on the film adaptation, which industry observers have pointed to as a reason the movie treats the illness with unusual care rather than reducing it to a simple romantic obstacle. Her hands-on involvement is credited with keeping the emotional specificity of tuberous sclerosis intact as the novel made its way to the screen.

How ‘The Last Sunrise’ Movie Portrays Ry’s Health Struggles

On screen, Ry’s condition becomes increasingly visible as her relationship with Julián deepens, with her physical symptoms taking a growing toll even as she tries to embrace living fully in the moment. The mother daughter dynamic between Ry and Isolde, her overprotective mother, adds another layer of tension, since Isolde’s fear over her daughter’s health collides with Ry’s desire for independence during what may be her last carefree summer.

Critics reviewing the Prime Video release have had mixed reactions to how the romance itself unfolds, with some finding the connection between Ry and Julián a bit rushed for a story carrying such heavy stakes. Still, even skeptical reviewers have acknowledged that the illness storyline gives the film a weightier emotional undercurrent than a typical summer romance, since Ry’s mortality is never far from the surface of any scene.

The film has drawn inevitable comparisons to other chronic illness driven romances that came before it, though Todd has been clear she wanted ‘The Last Sunrise’ to break from that mold rather than repeat it. Whether audiences feel the movie succeeds in offering a more hopeful take on serious illness storytelling has become one of the bigger talking points since its August 26 release.

The Real Life Inspiration Behind Ry’s Diagnosis

Todd’s openness about her son Asher’s diagnosis has added an extra layer of resonance for viewers who came to the film already aware of the author’s personal history. She has said that seeing Ry and Julián’s relationship brought to life on screen was one of the most rewarding creative experiences of her career, in part because the story carries a piece of her own family’s journey with tuberous sclerosis.

That real world connection has shaped how advocacy communities and readers with personal ties to the disorder are responding to the project, with many pointing out how rarely tuberous sclerosis specifically gets mainstream visibility in film or television. For a condition that remains widely unfamiliar to general audiences, ‘The Last Sunrise’ has already sparked conversations about representation that extend well beyond the romance at the story’s center.

With the film now streaming, audiences are left to decide for themselves whether Ry’s story lands as the hopeful, life affirming portrait of chronic illness that Todd set out to write. Did ‘The Last Sunrise’ handle Ry’s tuberous sclerosis and epilepsy in a way that felt honest to you, or do you think the romance overshadowed the deeper story Todd was trying to tell about her son’s own diagnosis.
