I got this one in a giveaway and though it took me a while to get through it, that was well worth the time. I am really amazed by what a feat of writing this is. The general feel is somewhere in between space opera and Mad Max, which is an impressive enough marriage as it is, but the author manages to keep so many different themes in the air. There's identity, as we're dealing with a first person narrator who finds "I" a fraught concept. There's all the various multiverse themes, which introduce multiple versions of the important characters, all handled with skill by the author to the point where I never needed to go back and look up where I am and who some minor character was. There's borders/ social class, recovery from abuse, inevitability vs the possibility of change, a wlw romance, family tensions, mentorship... There's even interesting and sensitive portrayal of sex work at one point. I'm not sure what this book doesn't have. It's so fast paced that I did large chunks in a single sitting because I couldn't find a place to stop, yet it somehow keeps track of everything. I think this author is very good at what she does and I look forward to her next work.
