Opinions about this blurb.

A mysterious portal opens and people are taken in by deformed figures and not return.
a researcher discovers that these people are dead and taken there could be no human survivors, because the intention is that the man is replaced by a perfect being would exist in place of the human being.
a group that escaped including this researcher and his son take refuge being hunted by deformed and survive and find a way to destroy the various portals.
Update : I intend to write more than one book.
