Once again Grace has managed to wrap me around another set of characters that keep me coming back for more and waiting with baited breathe! While this was NOT what I was expecting in the Virgin series, it stayed true to the Interstellar Brides series giving me characters that pulled me in and left me riveted from page to page. When I came to the end I am embarrassed to say that I shouts "NOOOOOOOO" for all to hear on the plane where I was reading.

Ex Output:
positive


Ex Input:
This supplement reduced the days of my colds! This has helped me so much and I couldn't live without it anymore. This is one of the best things I bought so far. I will be buying this again

positive

Mine came broken in several places. Cheaply made and probably wouldn’t last long if it ever did get loaded with a sub. Considering a bonfire tonight, I’ll post a video of it going up in flames later.

Ex Output:

negative
