Lord John and the Brotherhood of the Blade by Diana Gabaldon
This is book 2 in the Lord John series. It follows the timeline of the previous book and gives us more insight to Lord John Grey. We get to see his inner torment to be true to himself and his family without revealing his homosexuality to the world.
Again, I continue to enjoy these books. It looks like there are a couple of Lord John books that are not part of this series but were published before the next book in the series. I think I will go with publication dates and read them in that order and see where it gets me.
