March's end
(Book)

"The Harrows are a typical suburban family who...have borne a sacred and terrible charge. In the daylight they are teachers, doctors, bartenders and vagrants, but at night they are the rulers and protectors of the March, a fantastical secondary world populated with animate antiquated toys and sentient lichen. But beneath this dreamlike exterior lie dark secrets, and for generation after generation the Harrows have defended the March from the perils that wait outside its borders"--,Provided by publisher.
