The glorious 25th of May. If you have to ask, you weren't there.
But I'll do you a solid and tell you where to look: Terry Pratchett's beautifully written Night Watch. 29th in the Discworld series, it remains one of my favorite books and is always a go-to comfort read.
From the synopsis:
For a policeman, there can be few things worse than a serial killer loose in your city. Except, perhaps, a serial killer who targets coppers, and a city on the brink of bloody revolution.
For Commander Sam Vimes, it all feels horribly familiar. Caught on the roof of a very magical building during a storm, he’s found himself back in his own rough, tough past without even the clothes he was standing up in when the lightning struck. Living in the past is hard, especially when your time travel companion is a serial killer who knows where you live. But he must survive, because he has a job to do: track down the murderer and change the outcome of the rebellion.
The problem is: if he wins, he’s got no wife, no child, no future…
In writing about policemen Sam Vimes and John Keel back in 2002, Pratchett teaches us the difference between what is right and what is simply expeditious for the powers that be. He shows us the foolishness of mindlessly following orders and mindlessly following the rebellion, both.
In all honesty, This could have been written today, in the wake of the massive wave of police protests and the justifiable anger of Black Lives Matter. I only wish we here in Roundworld had a Sam Vimes to show us the way!
He even wrote "an old army song" for the rebels to sing. Beware, it is a soldier's song...
