#30 Square³ by Mira Grant

Once again Mira Grant hits it out of the park with a story that first gives you giant monsters but then settles down into a years long search for a sister caught on the other side of a barrier that produced those monsters.  Susan and Katherine become separated the day the monsters came and haven’t been able to contact one another since.  But a message gets through to Susan from Katherine, and Susan who has spent her life studying the barrier will do anything to see her sister again.   Life is different on the other side of the barrier and the children conceived and born around the barrier are of great interest to multiple governments.  Now think about what would happen if people born in the rifts could come through.  A good what if story and a setting I would certainly like to see explored some more.
