I would suggest The Hunger Games and its sequel. How about The Dark Tower series by Stephen King? This series combines element from several of Stephen King's other books into the series (example: Randall Flagg from The Stand is the antagonist of the first book, Pere Callahan from 'Salem's Lot appears in the fifth book, Ted Brautigan from Hearts in Atlantis is in the last book). It consists of seven books and one shortstory. The Gunslinger: Roland, the last gunslinger in a world like ours that has moved on chases the man in black across the desert, hoping he can catch him. The Drawing of the Three: Roland just encountered the man in black. This book begins a few hours after the first one ended. Roland finds three doors that lead to New York. Each door leads to a different time, and a different person is behind each door.Each person has some evil inside of them. The Waste Lands: Roland and his friends travel through mid-world in pursuit of The Dark Tower. Roland must draw a person from his past into this world, and they must travel through the city of Lud, a city abandoned many years before and inhabited with criminals now. They then need to get pass the waste lands. Wizard and Glass: Roland and his friends arrive in a world devastated by plague. Roland tells the group the story of his past, and the girl he loved and lost. Little sisters of Eluria: The short story from Everything's Eventual. Taking place before The Guslinger but after the flashback from the fourth book, Roland is injured and stays in a hospital where the patients never leave. Wolves of the Calla: Roland and his friends need to save a town from an attack by a gang of riders known as the Wolves. They learn things important throughout the rest of the series. Song of Susannah: Susannah's unborn demon child possesses her body and takes her to New York. The baby is about to be born, and her friends need to rescue her. The Dark Tower: Roland is very close to the tower. His time to get there and save his world--all worlds--is limited. The Crimson King is only days away from destroying the tower and all of the worlds the tower helps hold together.
