'How I Live Now by Meg Rosoff is a young adult fiction novel with a romantic twist.
Elizabeth (Daisy) is a fifteen-year-old Manhattanite who gets sent to stay with her cousins on a remote farm in the English countryside. This move occurs during a fictional third world war in the 21st century, and, although she is first enthusiastic about moving away from her evil stepmother, Daisy is homesick at first. Her homesickness only lasts for a little while before she and her extended family become closer and when Daisy begins to embrace her new home.
Not long after, Daisy finds herself falling in love with her cousin Edmond and, after realizing that the affection is mutual, the two begin a romantic relationship. Their happiness, however, does not last long while the war continues.
