The Search for FTL — Ted Iverson

Now, the four sons of the space travelers who lost their lives are thrust into the spotlight as the world's only private space corporation investigates the accident to determine what went wrong and how the impossible feat might yet be achieved.

Alec, the oldest brother, must battle internal demons as he seeks to determine whether to join his brothers to pursue what their parents could never accomplish: FTL, or traveling faster than light. Ty and Orion, the twins in the middle, must assume positions of responsibility far earlier than anticipated. And the youngest, Zach, must show that his immense intellect can usher in a new era of creativity for space travel and world security.

But in order to accomplish mankind's greatest achievement, the brothers must overcome a myriad of obstacles, danger and surprises as they seek their collective destiny in Mission to the Stars.
