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 is the second power bank I bought in past two month. The first one turns out the capacity is too big to travel by air. I got this one under 10000mAh. Tested a couple of times. Works great. Built in cables very convenient. Comes with a storage pouch good for travel.

Ex Output:
positive


Ex Input:
Awesome towel. Super absorbent and doesn't pull your hair. I have long fine hair and it can take a while to dry, but after using this and just air drying, it has cut my dry time more than half. I suggest getting 2 or 3 so you always have a fresh one on hand.

Ex Output:

positive
