Parallel Challenges - PARALLEL MISSIONS, #2

What would you do if you encountered a person from another universe-a parallel universe? Derek and Margo saved the life of such a man and were recruited by him to join a cause far greater than any they could imagine. The couple were given advanced training and equipment for the work they were asked to do. They planned to a month-long "vacation" to Europe with Tomas and his wife Judith. Thus, two couples from parallel universes team up to turn violence to peace in both worlds.  Their Missions utilize futuristic information and technology making it possible to travel through wormholes and space warps to intervene in crisis in distant locations while appearing to be on that European vacation.
"As it is in one universe, so it will be or has been in others."  They must contend with terrorists, governments, aliens, and saboteurs, all wanting to stop their Missions, eliminate them, and/or commandeer their Ship.  In the second book of the Parallel Missions series, encounters with alien species create both problems that could lead to disaster and opportunities that may increase their Team support.
