I love the time given to develop the friendship between Lancelot and Guinevere. I also really loved the personal development that happened for our Queen in this sequel.
The thing lacking for me was a romance. I'm still not on board with the Mordred train right now, and really thought I would be seeing more of a spark between Lancelot and Guinevere.
The cliffhanger was INCREDIBLE at the end, but this seems to be White's MO.
Wanted to love it more, but still enjoyed it.
