Navegator

Vasco Valseca is a scientific genius who has created Navegator, a unique software program that can pinpoint the exact geographical location of any internet activity - email, virus or hacking.
Navegator is hot property and only one copy exists.
Valseca is unaware that his precious invention is the focus of furious international activity: while a high-powered US project team is working on a similar program in a bid to combat computer-based terrorism, more sinister forces will stop at nothing to acquire such a valuable asset for sale to the highest bidder, whoever that may be.
In this fast-moving thriller where the work of a brilliant inventor puts his entire family at risk, the action switches from Washington to Mallorca, Monaco, St Petersburg and London as a series of ruthless plans, mix-ups and misunderstandings threaten to turn Navegator into cyber-terrorism's ultimate tool.
