City of Light - Shadows of Nar, #1

Destiny doesn't ask your permission. Sixteen-year-old Niah, and her younger sister Wish, are both clones. Together with a quirky artificially intelligent robot they are the only ones left on an ancient starship. With no memory of the mission, and her clone DNA disintegrating more every day, Niah is losing hope. When they crash on an alien planet, Niah realizes she may be more than she could have imagined.
The planet's inhabitants, forced to live under a dome, worship her unusual eyes and the echo of a dead man in her face. They know that she has the power to restore hope, and light, to their barren world but to do so she needs time. Time which is quickly running out. Will she be their redemption or they her destruction? If you like heart pounding action, adventure on other worlds, and characters you want to cheer for, grab a copy of City of Light, the first book in a dystopian young adult science fiction series by Rebecca Laffar-Smith. Suitable for teens and adults.
