Terri Blackstock's "Restoration Series" is dynamite. This fourth book in the series -- by far -- is the best one. All are wonderful, but this one really is a can't-put-it-down book. I highly recommend the series . . . . you won't be sorry.
This while series has been one of my all time favorites! Terri Blackstock is an AMAZING author and she keeps you right on the edge of your seat throughout the Restoration Series. I'd recommend it to ages from 15 to 80 but be sure to start with #1 and read all the way through #4.
