Norwegian by Night - Derek B. Miller

He will not admit it to Rhea and Lars - never, of course not - but Sheldon can't help but wonder what it is he's doing here...

Eighty-two years old, and recently widowed, Sheldon Horowitz has grudgingly moved to Oslo, with his grand-daughter and her Norwegian husband. An ex-Marine, he talks often to the ghosts of his past - the friends he lost in the Pacific and the son who followed him into the US Army, and to his death in Vietnam.

When Sheldon witnesses the murder of a woman in his apartment complex, he rescues her six-year-old son and decides to run. Pursued by both the Balkan gang responsible for the murder, and the Norwegian police, he has to rely on training from over half a century before to try and keep the boy safe. Against a strange and foreign landscape, this unlikely couple, who can't speak the same language, start to form a bond that may just save them both.

An extraordinary debut, featuring a memorable hero, Norwegian by Night is the last adventure of a man still trying to come to terms with the tragedies of his life. Compelling and sophisticated, it is both a chase through the woods thriller and an emotionally haunting novel about ageing and regret.

Dune - Frank Herbert

Melange, or 'spice', is the most valuable - and rarest - element in the universe; a drug that does everything from increasing a person's life-span to making intersteller travel possible. And it can only be found on a single planet: the inhospitable desert world Arrakis.

Whoever controls Arrakis controls the spice. And whoever controls the spice controls the universe.

When the Emperor transfers stewardship of Arrakis from the noble House Harkonnen to House Atreides, the Harkonnens fight back, murdering Duke Leto Atreides. Paul, his son, and Lady Jessica, his concubine, flee into the desert. On the point of death, they are rescued by a band for Fremen, the native people of Arrakis, who control Arrakis' second great resource: the giant worms that burrow beneath the burning desert sands.

In order to avenge his father and retake Arrakis from the Harkonnens, Paul must earn the trust of the Fremen and lead a tiny army against the innumerable forces aligned against them.

And his journey will change the universe.

Metropolis - Philip Kerr

Berlin, 1928, the dying days of the Weimar Republic shortly before Hitler and the Nazis came to power. It was a period of decadence and excess as Berliners - after the terrible slaughter of WWI and the hardships that followed - are enjoying their own version of Babylon. 

Bernie is a young detective working in Vice when he gets a summons from Bernard Weiss, Chief of Berlin's Criminal Police. He invites Bernie to join KIA - Criminal Inspection A - the supervisory body for all homicide investigation in Kripo. Bernie's first task is to investigate the Silesian Station killings - four prostitutes murdered in as many weeks. All of them have been hit over the head with a hammer and then scalped with a sharp knife.    

Bernie hardly has time to acquaint himself with the case files before another prostitute is murdered. Until now, no one has shown much interest in these victims - there are plenty in Berlin who'd like the streets washed clean of such degenerates. But this time the girl's father runs Berlin's foremost criminal ring, and he's prepared to go to extreme lengths to find his daughter's killer.    

Then a second series of murders begins - of crippled wartime veterans who beg in the city's streets. It seems that someone is determined to clean up Berlin of anyone less than perfect. The voice of Nazism is becoming a roar that threatens to drown out all others. But not Bernie Gunther's....

Weapons of Math Destruction - Cathy O'Neil

A former Wall Street quant sounds an alarm on the mathematical models that pervade modern life - and threaten to rip apart our social fabric

We live in the age of the algorithm. Increasingly, the decisions that affect our lives - where we go to school, whether we get a loan, how much we pay for insurance - are being made not by humans, but by mathematical models. In theory, this should lead to greater fairness: everyone is judged according to the same rules, and bias is eliminated.

And yet, as Cathy O'Neil reveals in this urgent and necessary book, the opposite is true. The models being used today are opaque, unregulated, and incontestable, even when they're wrong. Most troubling, they reinforce discrimination. Tracing the arc of a person's life, O'Neil exposes the black box models that shape our future, both as individuals and as a society. These "weapons of math destruction" score teachers and students, sort CVs, grant or deny loans, evaluate workers, target voters, and monitor our health.

O'Neil calls on modellers to take more responsibility for their algorithms and on policy makers to regulate their use. But in the end, it's up to us to become more savvy about the models that govern our lives. This important book empowers us to ask the tough questions, uncover the truth, and demand change.
