These Broken Stars by Amie Kauffman & Meagan Spooner
An epic, romantic YA space opera about two star-crossed lovers who must fight for survival on a deserted planet.
It's a night like any other on board the Icarus. Then, catastrophe strikes - the massive luxury spaceliner is yanked out of hyperspace and plummets into the nearest planet. Lilac LaRoux and Tarver Merendsen survive. And they seem to be alone. 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 won't be the same people who landed on it.
