 Wither was really amazing! The story takes place over a hundred years in the future, where girls die at the age of twenty, and boys die at the age of twenty-five, due to the fact that fifty years prior to the story, scientists were able to cure cancer. While these "first generations" were safe from cancer, when they gave birth, they discovered that science had come up with a new virus. 
 In the story, Rhine is a sixteen year old orphan living with her twin brother, Rowan, before she gets snatched off the streets to be sold to rich men in search of sister wives as a way of keeping the human race alive. 
 When Rhine is first captured, she holds fast to the hope that one day she will escape and return to her brother. While in captivity, she befriends Gabriel, one of the servants to her husband, Linden. The two eventually develope a romance, and decide that they will run away together 
 At her time spent in the mansion, she realizes that House Master Vaughn, Linden's father, is desperate to find a cure, and will destroy anything that comes in his way. Rhine even finds out that Vaughn was doing tests on Linden's first wife, Rose, without his knowledge, and that he killed Rose's baby, just because before she got pregnant, she wasn't sure weither she wanted to put a child through the awfulness at having to die at such a young age, even though, when she did eventually become pregnant, she grew attached to the child. 
 Rhine also befriends her two sister wives, Jenna and Cecily. Cecily is about thirteen years old, and is willing to do anything to stay in Vaughn and Linden's good graces, even if it means telling Vaughn that she saw Rhine and gabriel kiss, or carrying Linden's child. Jenna, on the other hand, hates the mansion, just like Rhine, because when she was snatched, her sisters were killed. She ends up dieing because Vaughn killed her when she was caught in the basement (where all of Vaughn's experiments take place) trying to find Gabriel for Rhine. 
 In the end, Rhine eventually does escape with Gabriel, with the help of Cecily, from the mansion.
