After being captured by ISIS fanatics in May 2013, freelance photographer Daniel Rye was held hostage for thirteen months in Syria. The ISIS Hostage is a moving and terrifying story that details Daniel’s friendship, suffering and survival under extreme circumstances.

The book illustrates how Daniel’s story is linked within European, American and Arabian history and how it feeds into one of the most significant challenges the Middle East will face in upcoming years.

In handing over a £1.3m ransom for Daniel’s release, Daniel’s negotiator carried Vismo Satellite Tracking devices to provide the support team with his position every 60 seconds. Tracking was integral to ensuring the safety and security of the negotiator. Positional updates along with Geo-Fence and Country Change notifications were shown in the operations centre in Europe and to the local support teams.
