Lydia's life on the ship has reached a turning point. For as long as she can remember, her android has trained her in farming and survival in order to prepare her to lead a human colony on a new world. But now that she's seventeen, the real work begins. One after another, Lydia is paired with a different human boy and tested for compatibility in one of the four climate domes on the ship. All she has to do is tend a garden and spend five blissful days with suitors chosen for her based on her physical and emotional preferences. Each boy is attractive and dedicated to her, and each test is engaging and challenging. But soon, Lydia begins to see cracks in the simulations and uncovers a truth her android was unwilling to share.
