The Magister by Sally Miller Gearhart
Now that the bailiwick outbreaks have been handled by Little Blue’s all-woman peacekeeping force in Book I, “The Kanshou,” a new threat to the planet emerges. The human species may be following in the footsteps of animal life, which deserted the planet on “Empty Monday” in the year 2021. Little Blue’s children are dying–in some cases, just after birth. In other cases, the children range from several years old to teenagers and exhibit no apparent signs of illness. In fact, they greet Death as a friend and go willingly, in song, singly or in groups.
