These Broken Stars, Kaufman Amie, Spooner Meagan

Lilac is the daughter of the richest man in the universe. Tarver comes from nothing, a young war hero who learned long ago that girls like Lilac are more trouble than theyre worth. But with only each other to rely on, Lilac and Tarver must work together, making a tortuous journey across the eerie, deserted terrain to seek help.
Then, against all odds, Lilac and Tarver find a strange blessing in the tragedy that has thrown them into each others arms. Without the hope of a future together in their own world, they begin to wonder-would they be better off staying here forever?

Everything changes when they uncover the truth behind the chilling whispers that haunt their every step. Lilac and Tarver may find a way off this planet. But they wont be the same people who landed on it.
