The Witness Protection Program has prepared a new identity for her and a marriage contract at a mining colony located on Esther, one of the moons orbiting Jupiter. The man who meets her there is not the groom she expected. Adam Elliot is obnoxious and hypocritical and looks like he got beaten up in a bar. But the memorial service soon reveals Adam's weak spot. Add some stellar sex, and these two decide that maybe marriage isn't so bad after all. But the hitman has already started working. A deadly game of cat and mouse unfolds on a frozen planet. Louise is determined to live long enough to lure the maniac away from her husband, with whom she may have fallen in love.
