Fierce Kingdom

A few quibbles (see below) but this did keep me turning pages. Tension galore as you read to see if Joan can save herself and her 4-year old son from being killed by two young gunman shooting people for sport at a zoo. Along the way they meet two other people who are also trapped inside who wind up providing invaluable help. Read this in one day (only 275 pages) and it's definitely one to check out.

My quibbles were (1) a third gunman (Destin) is seemingly behind the rampage but he never makes an appearance which made him seem superfluous - why even mention him if we never encounter him? (2) the setting is a zoo yet the author makes almost no use on any of the animals. It would have been interesting to see a lion or rhino escape, perhaps kills one of the perpetrators? (3) what in the world took the police so long to arrive?
