This book follows a similar formula to The Afghan, by the same author. There’s a terrorist threat to the western world- extremists brainwashed by a radical cleric are murdering prominent public figures. A former US marine (codenamed The Tracker) must track down the preacher (codenamed The Preacher) who only posts online – and eliminate him. The Tracker recruits a young, supremely talented hacker to help locate the source of the inflammatory material – he is codenamed Ariel (disappointingly, not The Hacker!)
The constraints put in place by politicians make The Tracker’s job harder – even having located The Preacher, he cannot order a drone strike because it is a built up area. So begins an elaborate plot to bring The Preacher out of his ‘fortress’ into a remote area, where he can be attacked. First, he is discredited in the eyes of his followers, by hacking his website and posting a fake message recanting his previous statements. Second, he is informed by a trusted friend (actually Ariel, aka The Hacker) that a local warlord has kidnapped a westerner and is prepared to sell – executing the man would re-instate his fearsome reputation. Having set the bait, the tracker must recruit a lethal army unit to seek and destroy The Preacher at his meeting with the warlord.

It’s always a pleasure to find a Nelson DeMille in the charity bookshop, and this one was excellent. The main characters are Paul Brenner and Cynthia Sunhill, who are military investigators (the former for homicide, the latter for rape). Their back-story includes an affair in Zurich when they last met and the love/hate relationship resulting from that continues throughout the book.
This is a Will Jaeger thriller, in which he battles to prevent the release of a deadly toxin that threatens global calamity, as well as continuing a long search to find his kidnapped wife and son. I haven’t read the first book in this series (Ghost Flight), but the story held together pretty well all the same. 
This is another excellent thriller in Connelly’s Harry Bosch series – it also features his half-brother Micky Haller.
This book is a sequel to Cold Blood, which I hadn’t read. That meant I had little understanding about why the main character, Nick Stone, and his team were being hunted by the mysterious “Owl” and what intelligence they were hiding as leverage to keep themselves safe.
The sub-title of this book is “Secret diaries of a Junior Doctor”, because Adam Kay was for some years a doctor in the National Health Service. His stories are often hilarious but they also reveal just what stress the doctors and the NHS as a whole are under. He had a successful career as a doctor, including several promotions – but ultimately, the crazy demands of the job took its toll on his well-being as well as his relationships and he had to leave.
Suppose intelligence discovered that a terrorist organisation was planning a fresh atrocity that would shock the world, but had no further leads to prevent it. Then it might be appropriate to take the longest of shots – send an agent into Iraq to infiltrate that organisation at a senior level, in the hope that the secret is shared with him. 
This book is set in the early days of the space race. Scientists have assessed the risk of previously unknown organisms being released on Earth (either alien bacteria brought back to Earth by rockets or Earth-bound organisms changed by exposure to the environment of space). The result is Wildfire – an underground facility with multiple levels of increasing levels of sterilisation, in which the scientists would research any such contaminated material.
I was given a lovely hardback edition of this book for my birthday. Whilst this book stands alone, I’m sure I miss much of the sentiment portrayed by the lead character, Peter Guillaume, because I haven’t read any of the George Smiley series before.
