I wasn’t sure of this book, yes another future book where everyone is doomed to die (has a post-apocalyptic feel to it that many books do) but I felt it aligned more with The Hunger Games. Boys die at age 25 for unknown reasons and girls die at age 20. The population has been over breed with people obsessed with creating a perfect race that now nothing is perfect and everyone dies young. So people are obsessed with creating a cure and a new generation so they kidnap young girls and force them into young marriages (polygamous) to make them into breeding factories
