Running Toward Home by M.B. Panichi

They escaped a murderous plot with their lives, but the danger surrounding former Special Operative Shaine Wendt and long-lost heiress Morgan Rahn is only beginning. At first the worst of their problems seems to be the endless media curiosity that follows them from Earth to Moon Base and back again. An assignment to Mars allows them to hide, but a mining accident leaves Morgan injured and Shaine convinced it's sabotage. Her prime suspects are from the colony of religious extremists not far from the site. Shaine's investigation uncovers the seething malice that she expected--and then something far worse. All they both want is a place to call home, but if they turn their backs will anyone be safe?
