You can find beta readers in facebook groups or on reddit communities for that kind of thing. I'm kind of floundering on that part, because I've had beta readers for my romance/erotica, but this is an entirely different genre, so I'm having to kind of scour for them since it's a whole new level of story.

My husband is going to be a beta reader (mostly because he's an awesome editor) and I have one other person who loves the genre who is going to read through it for me as well. I'm still looking for a few others. I've had a couple of people here on steemit who have been following my journey with this who have offered their services as well.

Good luck to your father! I hope you get your reading done so you can have Christmas :) Your dad sounds awesome, because that's exactly the kind of thing I would do!
