INDIGO by Tyree Campbell
Matt has a special gift that will enable him to avenge his brother's death. Kerise has another use for that talent, if only she can persuade him to abandon his personal quest and help her with a project called Indigo.
Echelon, a secret government project, also wants Matt because of his gift. But as he and other like him cannot be controlled, they pose a threat to national security. Orders go out to have them eliminated.
Interpol is on the lookout for Kerise and for the Indigo project. There is no place on Earth where Matt and Kerise and her associates will be safe. Nowhere on Earth...but they cannot be safe unless Matt commits himself to Indigo. And he's not about to do that...
