Below are my favorites with similarities to the Hunger Games - dystopian with a solid romantic element:
Blood Red Road (Dustlands Series) by Moira Young – 2012. In a post-apocalyptic future, 18-year-old Saba’s twin brother is stolen by black-clad riders. When tough-as-nails Saba launches a relentless search to recover him, she must fight for her life in gladiator cages, overcome enemies both creature and human, and learn to trust others for the first time. And try as she might, she can’t help but fall for the charming scoundrel Jack, who just may understand her more than she knows. The author tells Saba’s story in a raw first person format that blows you away. Must read for dystopian lovers!
The Shore of Monsters by David J. Nix – 2011. Five generations earlier, a horde of monsters nearly obliterated humanity. All males are dead or ruined by a monster plague; words like 'father' and 'romance' have lost meaning. When teenager Sky joins an expedition to the shore that falls apart, she must survive amongst the monsters that roam the ruins. She gets unexpected help from a very surprising source. Mystery, action, and romance follow!
The Forest of Hands and Teeth by Carrie Ryan – 2010. Seven generations have passed since the Return, a plague that reanimates dead humans into creatures that feed on the living. Teenager Mary lives inside one of the last enclaves of uninfected, protected by a chain link fence that surrounds her village. When the fence is breached, Mary flees the village with a small band of survivors. Their flight toward an uncertain salvation is both harrowing and revealing, as they try to determine if they are humanity’s last hope.
How I Live Now by Meg Rosoff – 2006. Fascinating novel about the outbreak of a 21st century world war as seen through the eyes of Daisy, a 15 year old American staying with her cousins on a remote England farm. At first utopian, the kid's existence degenerates into horror as the war encroaches on the farm. Through the several month period covered by the story, Daisy grows from a self-centered girl into a determined survivor. This book will leave a mark on the reader for years to come.
Unwind by Neal Shusterman - 2009. In post-war future, the abortion debate has been solved through compromise. Parents may elect to have their teenage children "unwound", a process where the teens organs and body parts are harvested for others. The story follows three runaway Unwinds, each discarded for behavior, religious, or economic reasons. As the trio embarks on a harrowing journey of escape, the reader will ponder very heavy moral questions, and wrestle with how much a bad decision can affect future generations. This is a masterpiece on every level!
Enclave by Ann Aguirre – 2011. In a shattered, post-apocalyptic world, 15-year old Deuce’s dream has come true. She has been named a Huntress, trusted by her community to brave the world outside of the sheltering tunnels and the threat of monstrous Freaks to bring meet to the tribe. The assignment is complicated by her pairing with the rebellious and handsome Fade, and a realization that the Freaks are growing more organized and cunning. Deuce and Fade must convince the tribal Elders of the imminent danger before it is too late.
Incarceron by Catherine Fisher – 2007. Incarceron is a prison so vast that it is self-sustaining. Generations of prisoners are born inside, doomed to a life in prison. The novel weaves two story lines: that of 17-year old Finn, who hopes to become only the second person to break out of the prison, and Claudia, the warden's daughter who hopes to escape an arranged marriage. When each discovers a crystal key, they find that they can communicate through the devices, and pledge to help one another. The story lines merge in a fantastic twist you won’t see coming.
