The sequel to the first Birds of Shangri-La feels less plot driven and more... Aside: Here's a look at the other protagonists' backstory. The first focused on the protagonists' backstory (at least in parts). Here the non-romantic interest gives their take.
The visuals while striking and well-drawn and their backstory, while unique, didn't hold the same flair for me as the first one did. I won't give too much away but the backstory does have the twist that sets it apart from other "sex-worker" backstories I've read.
Seeming to go at a slower pace than the original and featuring less intimacy, but more poignant moments of sensuality (as in plot specific, which was nice), it lacked in the hold that the first had for me.
However, I'd be curious to see where the story goes, especially after the ending.
I cannot say anymore, so go forth and enjoy. By the way, it does follow the sequence in storyline so I highly suggest you read the first volume before this.
