Oh! Hey, I liked this a lot, actually. 
 It sort of surprised me, given that I'd heard some really mixed things. But it hooked me right away and I didn't have problems getting into it like some other people have mentioned. And I flew through this... reading 500 pages in 2 days. So that should say something as well. 
 I think it really helped that I liked both Etta and Nicholas. They were likable and made logical choices and I connected well to both of them. The plot is... okay, but it's the "worldbuilding" for lack of a better term that's really neat. The internal logic of a time-travel system is a tricky beast, but Bracken pulls it off. 
 Yeah, I really enjoyed this. I'll definitely be picking up the conclusion soon because whoo-boy this does not even pretend to stand on its own!
