Finding Beta readers

[splothersdog]

I am writing a historical novel. Set in WW1 but very much from the home front perspective.
On draft number 52 billion ( obviously not but you get my meaning!!)
I hope to be querying next year. My question is how do you find beta readers??

Are you on Facebook? If so, you can join writer/reader groups for your genre and put a call for beta readers there.

That is really helpful! Thank you
