E. William Brown books in order

The System gave everyone on Earth a status screen, the ability to level up, and an endless supply of monsters to fight. To bad it seems to think the whole planet should be covered in adventure zones, and it doesn't believe in holidays or advance warning. But the civilization that fought the World Wars isn't going to go down without a fight, and these naked apes have a lot more tricks up their sleeves than just the ones the System gave them.

Of course, Tom and his buddies may not live long enough to see the outcome of this titanic clash between modern civilization and alien magic. Backwoods Alabama isn't the best place to be when the animals start turning into monsters, and the people who showed up for a hypnofetish meetup may not be the best companions. Oh, they're much better than random normies at exploring all the interesting things you can do with System-granted abilities. That's the problem...

My name is Alice Long, and I’ve always known I was different.

When I was little I used to climb up to the highest branches of the housetree at night, and watch the starships docking at the orbital stations high above. Forty meters off the ground, watching ships thirty thousand kilometers overhead, with senses that could pick out radar pings and comm chatter as easily as the ships themselves. It all seemed perfectly natural at the time.

There were other kids with mods at the orphanage, but nothing like that. I learned fast to downplay my abilities, keep my mouth shut and try to blend in. Even as a kid I knew not to trust the Matrons. What would they do, if they realized the Adjustments that were supposed to make me a meek little herd animal didn’t do anything?

Then I messed up, and gave myself away.

Now I’m on the run, hoping against hope that the Matrons won’t try too hard to find me. Hoping to survive all the awful things that can happen to a girl on her own in space. Kidnappers, slavers, pirates and yakuza - no matter where I go, trouble always seems to find me.

Good thing I’m not as helpless as I look.

Summoned to a world in the midst of apocalypse, Daniel Black would have his hands full just staying alive. Add in refugees, desperate soldiers, scheming nobles and a pair of thoroughly wicked witches, and life is going to be very busy indeed. Good thing he has magic of his own to even the scales. But will even that be enough

Surviving Ragnarok is challenge no matter what powers you have, and new problems keep cropping up. Demanding witches, genocidal monsters, divine feuds and local politics will all keep Daniel on his toes. But his enemies have made one crucial mistake. They've given an engineer who understands the nature of magic time to build things...

Gaea's favored children have put her ancient plan to cleanse the Earth of humans into motion, and Kozalin stands high on their list of targets. Uncertain alliances, scheming gods and an implacable foe will push Daniel to his limits. How far will the wizard from Earth go, to protect his family?

Without royal leadership Kozalin's defenders are falling into turmoil, but mortal problems pale into insignificance when the gods themselves take an interest in Daniel. With new enemies appearing everywhere he looks, and far too many secrets to keep, can even Daniel's magic save the day?
