This is the first book I have read for pleasure since September. Which kind of horrifies me, but there you go. I've actually started several, but mostly they haven't been singing to me.
This is a clever, plotty YA fantasy/mystery/adventure, unflinching about nasty realities of life on the street, full of juicy worldbuilding, engaging, fast-paced, with an outstanding heroine. I really enjoyed it a lot.
