The Dark Summer

The Dark Summer, taken place in Blackstone City, was an all out war between the followers of The Spinning Man, and the Ferals that stood against him, although no actual date is given in the books, throughout the trilogy, it is said that it was 8 years ago when it happened.

Summary
Before the Dark Summer, Blackstone was an extremely prosperous metropolis, but, after The Spinning Man killed Elizabeth Carmichael, and supposedly ended the Crow Line, he and his followers attempted to take over Blackstone, with what the humans thought was just a crime wave where animals acted up and started killing people and criminals patrolled the streets, but, when the Fox Feral, killed the Spinning Man, his followers were either killed, imprisoned, or went into hiding.

Aftermath
Although the Spinning Man was dead, and his followers were disbanded, the city of Blackstone never fully recovered, having lost many districts that they were unable to rebuild, and the Blackwater river was turned into a garbage heap, constantly flow out trash, but never making the city any cleaner.

And when it came to Ferals many lines were ended, or lost that current Feral, like Pips father, or lost the next candidat, like Emily‘s daughters. and some others were crippled during the war, like Madelein.
