The Gaia Effect by Claire Buss

SPSFC

In City 42 Corporation look after you from cradle to grave.  They protect you from the radiation outside the wall.  They control the food, the water, the technology and most important of all, the continuation of the human race.  Kira and Jed Jenkins were lucky enough to win Collection but when their friends start falling pregnant naturally, everything changes.  How long has Corporation been lying to them?  Is it really toxic outside the wall?  As the group comes to terms with the changes in their lives they discover there is a much more powerful and ancient force at work, trying to bridge the gap between man and nature.
