Chatterbox: Inkwell

Can anyone help me? I need a title for a dystopian novel I'm hoping to write. Not so dystopian so far I guess, but this is the quick little plot I came up with so far.

In the future America. A little bit like The Selection and the Russia parts in A Thousand Pieces of You (I highly recommend both, if you can deal with violence, swearing, and...um....romance stuff. ATPoY is more mature.) Main character is with family, doing normal family things in their house. Everything is like the present, except more futuristic devices. The tv flicks on, showing exploding buildings. All electricity then goes off and family runs out. They see everything destroyed and soon their home too. Now, some rebels of our government make the MC's family the royal family, so she's a princess. Reason why they are royal is either because they are rebels or are just special. Not sure.  No one can come in or out of America now. There is no modern technology (maybe just for cooking like ovens and the such and running water. Haven't decided yet.) so it's all like medieval times. One day, MC gets kidnapped. She is taken through a series of tunnels. There are millions of tunnels to create a rebel city of some sort underground. There, they have all the technology they lost and are going to overthrow the royals. MC falls in love, plot twists, action, and that's it. 

I know it sounds not fully thought out but u thought of the majority of it today in class.

The cover so far includes a circular tunnel and the silhouette of a girl. I'm going to type the title and my nickname for the website I use and then angle a tiara to make it look like its dangling from the title.  

If anyone could help with the title, that would be great!
