Summary
"Sherlock stared at his phone, still processing the abrupt end to the conversation. For the first time in over two decades, it wasn’t him hanging up, wasn’t him cutting the line. It was Mycroft. And something about that made Sherlock’s stomach twist, a cold, hollow feeling that sank deeper with every passing second. For all the control he had over his world, all the order he imposed on chaos, his older brother had just given him a reminder that Sherlock didn’t truly understand him, didn’t know what made Mycroft break. And that terrified him."
Or: In which Mycroft is kidnapped by Sebastian and Sherlock goes to save him

Summary
A year ago, Alec Lightwood walked away from Magnus Bane—heartbroken, in love, and unable to live with the walls Magnus refused to lower.
Now, one year after the Dark War, Shadowhunters are being found dead, their wings severed and bodies strung up. Warped traces of warlock magic cling to the bodies, and the Clave, in predictable fashion, is preparing mass arrests. Alec has seen this before. He knows how quickly fear turns to injustice—and how easily the Downworld could fracture under it.
There’s only one warlock powerful enough, knowledgeable enough, and infuriating enough to help him stop it before another war begins. Unfortunately, it’s the man who hasn’t spoken to him in a year.
Magnus never expected Alec to appear at his door again. But with warlocks being blamed, Shadowhunters dying, and old wounds reopening with a single look, he has a choice to make: protect his people or protect his heart.
Because something is hunting Nephilim—something that knows how to take wings and how to start a war. And Magnus and Alec will have to face it together, whether they’re ready or not.

Summary
Centuries before Magnus Bane ever cast a spell and long before the first Shadowhunter drew a rune, the dragons walked the earth—ancient, neutral guardians of balance who refused to side with angels or demons. After being hunted and misunderstood by both Nephilim and demons, the dragons retreated to a hidden island and fell into a deep sleep, fading into myth.

Who Is William Herondale?: A Presentation.
After weeks of Magnus being secretive, furtive and giggling to himself in the middle of the night, Alec is starting to suspect that his boyfriend may be going a bit mad.
But, when he and his friends wake up in the middle of Magnus' living room with an odd taste in their mouths and no memory of how they got there, things turn from weird and outright creepy. The addition of a very confused Brother Zachariah and the mysterious but calm Tessa Gray, and the group begin to suspect that Magnus is once again up to something.
The lights dim and a projector appears, displaying the title page of a PowerPoint presentation they will never forget. A presentation that will answer one of Alec's most burning questions in his and Magnus' relationship: Who is William Herondale? -

Summary
(tags will be updated as story progresses)
Magnus Bane has loved Alexander Lightwood since the first time he laid eyes upon the man. He'd expected to spend, at least, all of Alec's life with the the hunter, so when Alec dies while on mission, Magnus spirals into what he thought he should do and what was morally correct, unaware of the truth that remained hidden from him by the one who his heart longed for.
Or, in which, Magnus Bane gets whiplash from grief and is left more confused than anything else, knowing that now he has to teach a new vampire how to be one, despite being so under prepared to do such a thing, while his mind spirals further into becoming a monster.
