4.5 stars. 
 I. Oh. I am actually surprised by how much I enjoyed this. Like really. I expected it to be a fun YA romp, but I ended up reading the entire thing in one sitting without at all meaning to. 
 There were some wicked twists and the stakes felt appropriately high. The world-jumping was really cool, with each world feeling different. And there's this heavy implication about like intertwining fates and the people you know and fall in love being similar across dimensions and OH BOY. It is no secret that I am 1000% into that nonsense. 
 So yeah, I loved this. I had plans to go scoop up book 2 from the library, but those were dashed when I found someone else beat me to it. Alas! I will be picking up the sequel and soon! (And may have to strongly consider buying the series if book 2 is good, because UGH THOSE COVERS, they're so gorgeous.)
