Parallel Promises takes the Team to Caledronium, a distant planet, to answer an SOS, turning defeat and desperation into hope. Promises made become promises kept as Team members respond to multiple crises in alien worlds and around the globe called Earth. Their return to Earth takes them to a mining disaster in Wyoming and gives them a day to visit a famous town on Margo's bucket list. Sicily, Cameroon, Korea, and Antarctica are among the countries to which Parallel scientists send various Team members for interventions. The funeral of an elderly neighbor with promises of eternity precedes wedding promises in Germany. A communication crisis threatens to jeopardize and derail Team Missions, bringing two old friends together. A fantastic rescue deep within a glacier on a reactivating volcano becomes another promise kept.
