Most good stories start with a fundamental list of ingredients: the initial situation, conflict, complication, climax, suspense, denouement, and conclusion. Great writers sometimes shake up the recipe and add some spice.
Exposition
Final Boarding Call
We first meet Gemma when she's fighting in the airport with her mom over whether or not her shirt is too low-cut. There's also a creepy guy following them everywhere, which makes Gemma a little bit uneasy. When he offers to buy her coffee because she doesn't have the right currency, though, Gemma is quick to accept.
Rising Action
That Definitely Wasn't Sugar
Things take an unexpected turn when Ty drugs Gemma and kidnaps her, taking her to Australia to live on an isolated property in the middle of the desert. Wow. Suddenly, fighting with her mom about her clothes doesn't seem so important anymore.
Climax
When Snake Handling Goes Bad
After a month or so of being kept against her will at Ty's place, Gemma gets bit by a snake as Ty tries to wrangle it. Because Ty is a weirdo, he has antivenom stockpiled and uses it to stop the infection, but it doesn't do any good. Ty makes the choice to return Gemma to civilization rather than have her potentially die—even if it means getting caught.
Falling Action
Stockholm Syndrome Strikes?
Back in the real world, Gemma finds herself struggling to recover from both the physical damage of being in the desert and the emotional aspects of her kidnapping. On one hand, Ty kidnapped her and that's totally not right. But, on the other hand, she finds that she has developed genuine feelings of concern and affection for him. She spends most of her time fighting with her parents, doctors, and herself about the true nature of Ty's character.
Resolution
Gemma Levels the Verdict
We learn that this whole book is a letter Gemma has written to Ty to help process her feelings. While she debates lying to the jury and saying that she willingly went with Ty, she instead decides to tell the truth but also share the side of Ty that convinces her he isn't all bad. She tells Ty that she hopes he can eventually become the man she's seen as a result of this experience.
