The trouble with most thrillers is that the characters are usually cold, heartless human beings, operating in vicious, grey netherworlds of dehumanised, numbing violence.
This cannot be said of 'On Dangerous Ground', which is a thriller, a romance, a travel adventure, a reflection on the paradoxes of the Vietnam War, an exploration of mother-daughter tensions. It is a story of extraordinary events happening to ordinary, readily recognisable people.
Pru is an ordinary suburban middle class Englishwoman thrust slowly but unavoidably into a tense, life-or-death adventure, meeting flawed heroes and complex villains along the way. Sue Cook takes great care to craft each and every character in a credible, three-dimensional way, baring the paradoxes of human beings and their inter-relationships. Pru's adventures, although extraordinary, are both thrilling and entirely believable, with no loss of a sense of reality. The scenes in the Vietnamese countryside are particularly well evoked: the mud and rain, the grinding poverty, inhuman oppression (past and present), the crushing of poor people, desperation, humanity and compassion. The reflections on the impact of Agent Orange on today's children evoke anger and outrage.
The book is well paced. I remember enjoying the narrative as Pru began her visit to see her daughter in Vietnam, and hoping absurdly that nothing bad was going to happen (although I knew that something was inevitable). In this way, the tension, fear and adventure creep up on the reader, much as they do on the central character.
I learned a lot about Vietnam, its people and culture. The Vietnamese people are described poignantly and sympathetically, as are the American war veterans struggling to atone for the absurdities of a brutal, dehumanising and incomprehensible conflict.
There is action and adventure as good as any airport mass-market paperback, and the sex is skilfully understated, and no less powerful and erotic. What the book thankfully lacks is any gratuitous, brutal violence, without glossing over the pain and suffering in Vietnam. I don't recall a single shot being fired in the narrative (except in Vietnam war flashbacks).
This novel was a thoroughly good read; enjoyable, moving and ultimately uplifting. Highly recommended.
