Chris Ryan 
Agent 21: Reloaded [EPUB ebook] 
Book 2

Some authors just write about it. Chris Ryan has been there, done it, and lived to tell the tale. This is the second in the action-thriller Agent 21 series by the real-life SAS hero.In the year since Zak Darke was approached by a shadowy government agency to become Agent 21, his world has changed completely. But there is no time to reflect on this – the undercover operations go on. Zak is sent to a port in west Africa, a known terrorist stronghold, under the guise of working ona charity volunteer project. But charity work could not be further from Zak’s real mission – he must sneak onboard an enemy ship, gather information – and then destroy it. Never has Zak’s training been more useful: Trust nobody.
