Seriously guys, this is one of my FAVORITE books. i LOVE SAVVY! Anywhos, it's about this girl Mibs. Mibs' whole family has these awesome powers like her brothers can attract lightning and form HURRICANES (btw: they have to be home-schooled by age thirteen because that's when they get a power). So Mibs (oh, I forgot how she got there!) goes on this long journey on this old (pink!) bus. And in the end she gets her power and it is...... Mibs can actually HEAR ink!
PS--sorry, I read this almost a year ago, so it's not very fresh on my mind. But I do remember I liked it very much! <3
