Elites of Eden (2)
Yarrow is an elite: rich, regal, destined for greatness. She’s the daughter of one of the most powerful women in Eden. At the exclusive Oaks boarding school, she makes life miserable for anyone foolish enough to cross her. Her life is one wild party after another…until she meets a fascinating, lilac-haired girl named Lark.
Meanwhile, there is Rowan, who has been either hiding or running all her life. As an illegal second child in a strictly regulated world, her very existence is a threat to society, punishable by death…or worse. After her father betrayed his family, and after her mother was killed by the government, Rowan discovered a whole city of people like herself. Safe in an underground sanctuary that also protected the last living tree on Earth, Rowan found friendship, and maybe more, in a fearless hero named Lachlan. But when she was captured by the government, her fate was uncertain.
Rebels of Eden (3)
Rowan is finally in Harmonia, an Earth-friendly, sustainable commune in the wilderness she always believed was dead. Even in this idyllic world, she finds no peace. Harmonia has strict rules--and dire consequences. Thinking about Eden is forbidden, but she's determined to rescue the loved ones she left behind. Though they are in terrible danger, her pleas for help are ignored.
After months of living as one with nature, a shocking reminder of her past pushes Rowan to act. With the help of new friends, she infiltrates Eden. What she discovers is even worse than the situation she left behind. In the chaos of civil war, Rowan and her friends join forces with the second children and other rebels trapped inside. They fight for their lives, and for the future of humanity in this broken Earth.
