The Untethered by S.W. Southwick.
Here is the description from Amazon:
A juvenile delinquent chases his dream to build the greatest aircraft in history--and the world tries to stop him. A rising political star runs from her childhood dream--and the world encourages her on. A self-loathing geneticist hides below the streets of Las Vegas--and rebels against the whole world. An artist tries to make his father proud--at the cost of everything he loves.
When all four lives collide, each must make a choice. And the world will never be the same.
--I really enjoyed this book. Highly recommended.
