Despite my 👂 reservations, of all the weird quasi-fringe GHB factions, I would say Free Peoples is right up there for being reasonably likely to get a Tome. But...
We don't know if they will
If they do get a Tome, we don't know what that will look like - perhaps their whole army play style changes, or perhaps they get lumped up into some of the other factions. Anything could happen
I don't know if would recommend Free People (or any other GHB army) for beginning players - even if they are not new to the hobby in general. Players could be spending lots of money in things that either won't be good in the future, or would end up being phased out of the army somehow.
