Ripping action and great characters. I suspect the YA genre is full of unique snowflake loners and a short description of Raven places her firmly in the black-clad, loud music listening, crotchety loner camp but she's more than that, intriguing and capable and and hard, able to learn - human skills as well as technical skills - and not simply a soft inside protected by a hard shell. Keen to get my hands on the next book.
