Brain Candy Alert!
First, take two alien peoples (Greens & Grays), living seriously underground in NYC for decades who are about to re-stage the Armageddon of their collective past. The only way to Stop The War? The sacrifice of a 12-year-old girl (Melantha Green)....but wait, not everyone favors this move so the girl is abdu.....spirited away at the 11th hour....leaving many unhappy folks, some bent on Revenge
Next, take one Yuppie couple with a creaky marriage, on the way home from a tense "night out"...who are handed said girl at gunpoint and told to "Take her. Protect her"...and the games begin. Because everyone and his brother is on the lookout for the non-sacrificial lamb.
With all this potential for Urban mayhem....let's not forget the NYPD....enter Detective Fierenzo.
Then add some car chases, convoluted subway rides, Hammerguns, Shrieks that can be deadly....at least two abductions..a country idyll that is anything but...allusions to Greek and Norse Mythology....A Romeo & Juliet angle that's "oh so sweet"...Evil Meanies...treachery in the ranks...and an ending that seemed a bit tame to me....Peace is Declared and God Bless Us Everyone...Like i said...Brain Candy!!
I have not read anything else by Mr Zahn, but i get the impression that this was a departure for him, from Hard Sci-Fi..I found the Hard angles herein a bit far-fetched...thought this one was more a Police Procedural with Alien overtones. Since it was published in 2004..the shadow of 9/11 was ever-present..but did not detract from a pleasantly wild ride.
