The Last Boy and Girl in the World is about a girl named Keeley. Her town of Aberdeen is located near the river. Over the spring, Aberdeen has had a lot of rainfall, so much that the river starts to flood into the small town, and people are forced to evacuate the town. Before the flooding happens, Aberdeen High School's Key Club put sandbags on the river, so the flooding won't be so terrible. Keeley just happens to stand by her longtime crush, Jesse Ford. In this novel, Keeley needs to learn how to be a good girlfriend and a good friend during this crisis period. 
 I absolutely loved every single second of this novel. It was super funny, romantic at times, and dealt with real world problems.
