Omega Alpha by Kristen  Landon

A secret organization. A plot to release a deadly virus. Only Ethan can stop them.

What would you do if everything you thought you knew about your childhood, your parents, and your family turned out to be a lie?

Thirteen-year-old Ethan Turner is about to find out.

Ethan survives an environmental terrorist attack, but the toxic gas he breathes during the attack triggers memory flashes from when he was very young. The problem is, those memories don’t match up with the life he knows. He starts to notice and uncover clues that lead him to believe his parents are hiding a terrible secret from him.

With the help of two close friends, Ethan continues to search for the truth—even when it lands him right in the middle of a group of environmental terrorists who are about to release a pandemic-grade virus on the world.

The truth about his family and his past could cost Ethan his life as well as the lives of everyone he cares about. He has to make the impossible choice—save himself and those he loves or save the world.
