I didn't think there was excessive foul language (maybe due to my time in the military, doh!). I liked the concept and the characters and I did laugh a lot. The runaway situation at the beginning seemed a little overdramatic but with what happened to her, I totally understand. 
 My only big bummer about the book: I was so excited to start #2 and so I read the sample chapters. After I finished them I had no desire to read any more of it. I might try and read it later, though.
