It is a bit long and drags in places; Sydney is annoying at intervals as she displays a lot of angst over trusting herself but repeatedly sticks her nose into the case long after being dismissed from her forensic duties. There are the typical mad car chases, escapes from certain death at the hands of the evil henchmen, and a harrowing scene in the underground burial chambers. A little romance with one of the ATLAS operatives is developing and the book ends with hints that there will be a sequel involving Griffin.
I might be tempted to check out the next book in the series. You don't have to read the first one to understand the characters or the plot of this novel as it can stand alone.
