​"An excellent read. Lawson Pacheco is used to fighting a secret war, but when he finds a secret that feels wrong, he won't rest. Asking questions costs him and those he loves, but the answers are more important. R.J. Pineiro's story starts out strong, and then it gets better."
--Larry Bond, New York Times Bestselling author of Red Phoenix
