January 29, 2035. That’s the day the comet is scheduled to hit—the big one. Denise and her mother and sister, Iris, have been assigned to a temporary shelter near their hometown of Amsterdam to wait out the blast, but Iris is nowhere to be found, and at the rate Denise’s drug-addicted mother is going, they’ll never reach the shelter in time. Then a last-minute encounter leads them to something better than a temporary shelter: a generation ship that’s scheduled to leave Earth behind and colonize new worlds after the comet hits. But each passenger must have a practical skill to contribute. Denise is autistic and fears that she’ll never be allowed to stay. Can she obtain a spot before the ship takes flight? What about her mother and sister? When the future of the human race is at stake, whose lives matter most?
