Exodus — Kate L. Mary

The end is only the beginning...It's the final days of Earth, and Tessa has made her peace with dying. Her life has never been a fairy tale, so it makes perfect sense she'd perish with most of the people on the planet. Except luck is finally on her side, as is her Knight in shining armor, Ty, who puts his own life on the line to make sure she gets to Salvation-1 before zero hour.The ship is supposed to be humanity's chance to start over, but making it off Earth is only the beginning.Forty years in hyper sleep, a new planet in a new galaxy, and a whole new set of challenges. When nothing turns out out the way they thought it would, Tessa and the other survivors once again find themselves fighting for their lives. Only this time if they lose, there's no chance of escape.
