Not books, but several of the premium 'paid for' (even by subscribers) productions from FaithlifeTV are available on the Logos YouTube channel.
Perhaps they will be set to free for Faithlife TV subscribers soon, but for now you can view them on YouTube.
Heisers Angels series, Demons documentary, Unseen Realm documentary.
There is also 'Authorized' by Mark Ward that is normally just available to just subscribers.
And some Sean McDowell Is God Just A Human Invention?
questions that are available to all normally.
