The book is an attempt of a Royal Electrical and Mechanical Engineer (REME) to recount his approximately two years of service in Libya and Gibraltar. It is basically a fairly idyllic, relaxed young men's dream - some live weapons shooting interspersed with lots of scuba diving, copious amounts of beer, the odd dance with senior officers' daughters and regular camping in the desert.
There is certainly also respect towards the local population (much more so than in decades since), which is refreshing to read about. But in essence you have a memoir of young men trying to kill lots of free time, with very relaxed officers turning a blind eye over the wilder ventures.
It is certainly not something for readers looking for action sequences and firefights. On the other hand it will probably allow pleasant memories to resurface in those who have served at the time, especially in warm, relatively peaceful far flung corners of the empire.
