There's also a fanfiction where Magneto senses danger approaching Quicksilver during a battle. He quickly creates a magnetic field around Quicksilver to keep him safe. This story really delves into the father - son relationship between them, highlighting Magneto's instinct to protect his son.
You can start by looking on fanfiction.net. It has a large collection of X - Men related fanfictions, and there are likely many that focus on Magneto being protective of Quicksilver.
In certain comic arcs, Quicksilver's fate is that of death. But comic storylines can be complex and sometimes characters come back or alternate realities exist where they are still alive.
One of the best Quicksilver stories is his appearance in the 'X - Men' comics. He shows off his super - speed in really cool ways, like running circles around his enemies. His cocky attitude also adds a lot to the story.
One idea could be a story where Nightcrawler and Quicksilver team up to stop a powerful villain who is causing chaos in the city. Their different powers would complement each other well. Nightcrawler could use his teleportation to surprise the enemy and Quicksilver could use his super speed to quickly disarm any traps or threats.
I don't know who the author of the 'quicksilver novel' is. There are so many novels out there, and without more specific information, it's hard to determine the author.
