Milk Magic 4: Heart of the Farm

Erin is back home from her mission to Greendale, and happy to be back with Paul. She's now back in her old environment, her old apartment and job, but things... feel different. But the assassins are still after her! For her safety she is taken to a farm, the same one Paul has been visiting. Paul's been going to this same farm while she's been gone and still seems to know more about her than she does. Even with how much she's learned, and changed. There are restrictive rules though, different social rules, but Cows who immediately feel like family. News comes to her that Paul got hurt, and she is stuck on the farm for a while! Will Erin learn what it is to be a Cow on a farm, and that she might not hate it? Will she ever be free of them? Or find a way to be more than just a Cow? Or will she be stuck there, forever treated only like a Cow, restricted from using magic, most of her brain, and being treated more like she needs to be coddled than listened to?
