The third in the Kindred series finds two angels selected to come to Earth to observe, learn, evaluate, interact, and then report back to God so that life on this planet with all these creatures and things, and all the stuff always going on, might well improve. Now, if the two angels thought this was going to be a fun excursion, they were a bit optimistic. Follow Leonard and Ellen (who goes by "L"), and who don't get along all that well at any given time, as they pay a visit to earth, explore a lot of nooks and crannies, before returning home to give their big report.
