So, the bus internet ate my intial review of this so this will be quite short. 
 I really enjoyed this book overall. The intial set up did feel a bit slow and draggy due to the info dump, but it picked up good after that. The world felt really well built and well researched where it tied into Eastern mythos, without feeling too familar. The characterization was really interesting as well, Goodman's work with gender I found in Lady Dela was intriguing but it was even moreso to see Eon/Eona's struggles. I've seen many reviews touting this as girlpower book (which I wouldn't deny) but at the same time Eon's focus on being male really plays around with that idea and harkens Lady Dela's thoughts on balance. 
 The only issue I had aside from the intial set up was scene continuity. I found, mainly with actions scenes, that I'd lose who was speaking or where we were located, either because I wasn't reading close enough or was lead astray by some lines. 
 All in all though I really liked it and am super interested in reading the sequel to see how this turns out.
