Arcadian Genesis is a novella, not a novel, and functions as a prequel to the series featuring Alex Hunter and his elite HAWCS.
I haven't read any of this series, but the novella was fast-paced and action-filled. The mission of the HAWCS is to rescue a Chechen scientist who wants to defect with important information. Alex Hunter's team is not alone in searching for the defector, and the Russian team has no compunction, no compassion. It is best not to get between the Russian team and their prey.
Since I've not read any of the novels in this series, I can't appreciate the information Arcadian Genesis provides, but evidently fans of the series are happy to have some of their questions answered.
The first book in the series is Beneath the Dark Ice; the review sounds like a good action/thriller, and I'd much rather read a novel than a novella.
