Perfect Little World by Kevin Wilson
Pregnant by her high school art teacher, Izzy Poole decides to join the Infinite Family Project because of the stability it will provide her and her newborn son, Cap. The project is the idea of Dr. Preston Grind and billionaire Brenda Acklen. Basically, ten families with babies agree to live together for ten years and raise the children communally, with the kids not knowing who their real mothers and fathers are for the first several years. Izzy finds herself fitting in well with the rest of the parents, but starts to develop feelings for Dr. Grind. Not surprisingly, cracks begin to form in the relationships between other participants, too. Will Dr. Grind succeed in his vision of forming lifelong bonds, i.e. families made of people who aren't related? Perfect Little World is an intriguing story about an unusual community and the moral compromises that keep it together.
