The Hunger Games (1trilogy)

In the ruins of a place once known as North America lies the nation Panem, a shining Capitol surrounded by twelve outlying districts. The capitol is harsh and cruel and keeps the districts in line bg forcing them all to send one boy and one girl between the ages of twelve and eighteen to participate in the annual Hunger Games, a fight to the death on live TV.
Sixteen-year-old Katniss Everdeen, who lives alone with her mother and younger sister, regards it as a death sentence when she steps forward to take her sister's place in the Games. But Katniss has been close to dead before--and survival, for her, is second nature. Without really meaning to, she becomes a contender. But if she is to win, she will have to start making choices that weigh survival against humanity and life against love.

SUSPENSE and PHILOSOPHY.
ADVENTURE and ROMANCE.
