The author's 2024 thriller book unfolds from Lyla's point of view, following the main character as her boyfriend, Nico, convinces her to join him in a reality show competition on a private island.

Lyla's real plan is to get eliminated early on, leaving Nico to team up with the other contestants and claim his fame. However, things go awry on day one, when Nico is eliminated and Lyla isn't. From there, even more goes wrong, with a terrible storm crashing through Ever After Island and leaving the survivors stranded.

Who Survives Ruth Ware's One Perfect Couple (& How)

The Final Survivors Band Together Against Conor

One Perfect Couple opens with 10 contestants traveling to Ever After Island, but only four of them remain when Ware's 2024 novel comes to a close. The survivors of the reality competition gone awry are Lyla, Santana, Angel, and Zana. And it's not by luck that these women make it off the private island. They're forced to kill Zana's abusive boyfriend, Conor, before they're able to find help. Conor spends much of the book installing himself as the leader on Ever After Island, and he becomes increasingly tyrannical about the food and water supply.

It's mostly due to Conor that the other contestants perish while on the island, though an influencer named Romi is crushed during the storm. The others meet more sinister ends. Conor kills Angel's boyfriend during a fight, and he drowns Santana's friend, Dan, after Dan discovers that Conor took her insulin supply. He also gains the trust of a professor named Joel, but Joel dies by suicide after realizing he was wrong about Conor. Conor's physical strength makes it difficult to overcome him, but Lyla, Santana, and Angel are left with no choice after he starts keeping food, water, and medicine from them.

At this point, Zana is in no state to stand up to him, but the other three women make a plan. They decide to put Angel's sleeping medication in coconuts they collect for Conor, then stick him with Santana's last vial of insulin while he's sleeping. Since he isn't diabetic, this sends his blood glucose levels to a deadly level. Unfortunately, Conor wakes up as Lyla and Santana are enacting this plan. As he's chocking Lyla, Zana smacks him in the head with a bottle. The two fall into the water, and Lyla manages to save Zana. Conor, on the other hand, loses consciousness and drowns.

Santana, Lyla, and Zana all survive their confrontation with Conor, and Angel forms a plan to call for help. The beginning of One Perfect Couple teases Angel's background with cars, and the ending of the book reveals her father owned a garage. With her knowledge of car batteries, she surmises that the group can use the acid in their dead radio's battery to heat it up — enough so that it can give it a final burst of energy. She successfully manages this, signaling a boat to come save them.

Why Conor Tries To Kill Everyone On Ever After Island

He Knows He Can't Risk Witnesses Leaving The Island

Ware's book makes it clear that Conor is abusive and controlling, but it doesn't seem as though he steps onto Ever After Island with the intent to kill the other contestants. His deadly encounter with Angel's boyfriend, Bayer, occurs during a fit of rage. From there, though, Conor realizes that he can't allow witnesses leave the island. As he's a high-profile YouTuber, their accounts of his actions could ruin his career. They could also put him in prison, which is likely why he makes Joel steal Santana's insulin.

Once Conor kills Dan, he becomes even more stingy with the food and water supply, likely because he can't explain away both deaths by claiming self-defense. With no help in sight, Conor is also probably hoping to have more resources with fewer people on the island. But when he allows a ship to pass without attempting to get its attention, it's clear he plans to do away with everyone but himself and Zana before being rescued. This is why the survivors are forced to overpower him during One Perfect Couple's ending. And funnily enough, they're actually on the island because of Connor.

Baz's Secret Plan In One Perfect Couple Explained

The One Perfect Couple Creator Wanted To Expose Conor

After Lyla, Santana, Angel, and Zana are rescued from Ever After Island, the four of them realize why Baz set up his reality show in the first place. Santana mentions that she went to school with a girl who dated Conor and later died by suicide. Baz turns out to be that girl's uncle. Apparently, he wanted revenge on the man who groomed and abused her. The women realize this when Lyla comments that she and Nico never received a contestants' package prior to the show.

As it turns out, they were a last-minute addition. Another couple was initially supposed to participate, and they had something in common with the others: a connection to Conor. By placing participants with knowledge of domestic abuse and Conor's background together, Baz hoped to expose the YouTuber. However, he and his crew didn't plan for the storm or anything that came after. Baz and the other people behind the underfunded, sketchy reality show don't survive; their boat back to the mainland sinks during the storm. Baz's plan also doesn't work, as the whole situation turns Conor into a hero.

Why Zana Writes A Diary Fabricating What Happens On The Island

Making Conor A Hero Helps The Women Evade Suspicion

Although Conor is the villain of One Perfect Couple, his death turns him into a hero during the book's ending. As the women await their rescue from Ever After Island, Zana panics about her part in Conor's death. She believes that the authorities will put the pieces of what happened on the island together, implicating her and the others in Conor's demise. That's why the four decide that Zana should write a diary, fabricating everything that happens on the island. She reworks the tragic chain of events, turning Conor into a hero who no one would have reason to kill.

Whether this would truly work is questionable, but it seems to pan out for Ware's characters. The women are able to return home without facing charges, but it's at the cost of making Conor into an even bigger celebrity. But with One Perfect Couple's overarching abuse storyline, one thing is clear: surviving and sisterhood are more important than everything else. That's the message that Ware's May 2024 book sends during its final chapters, even in the face of its bittersweet ending.

What Happens To Nico At The End Of One Perfect Couple

Lyla's Boyfriend Dies With Baz & The Crew

Nico exits Ever After Island before the storm hits, but this isn't enough to save Lyla's boyfriend from its impact. Nico dies on the ship with Baz and the crew, leaving Lyla alone at the end of One Perfect Couple. This is another bittersweet development, as the book makes it clear that the two would never have worked out. Still, Nico's apology texts also underscore that he isn't the type of guy that Conor is — and that his demise is just as tragic as the other characters'.

For a novel with feminist themes, it's fitting that only the women survive One Perfect Couple. Ware's latest thriller makes a powerful statement with this, as well as their sisterly pact to protect one another — one that feels reminiscent of Big Little Lies' ending. After a tense survival story, it strikes the right balance between being believable and being satisfying. That's all readers can really hope for when it comes to thrillers.
