I'm divided on this one.
I liked the writing. I liked the stab at representation and consent issues. New takes of old tales are always an interest to me, and the sci-fi slant is just more win.
I could not get over Earland. On his own, he undermines most of the good bits about body-autonomy, consent and chauvinistics screenings. There's this bit where the doc passes on testing the virus/cure combo on a male cyborg ostensibly because he's too old (and in his mind, ostensibly because he has a son), but then gets all gung-ho on testing the teen girl, and a female colleague implies it is because he's a chauvinistic ass. But hey, no! That woman was obviously wrong and overreacting! (oversensitive feminists!) He just knew that the immune one he was looking for would be a cyborg teen girl. He's not racist or anything. It is just a pity that the easiest way to find her was to implement a draft on a group with little body autonomy and they... well... die. The princess (and a cure... that too) must be found! He's just working with the system! Honest! (I kept thinking of The Immortal life of Henrietta Lacks, and also the Nuremberg Trials, ain't he a peach?)
The other bit that I did not like was the very end.
And I knew it was a series, but I still hate books that do not resolve the main plot. I like series with myth arcs and more or less self contained volumes. I can count the amount of books I "forgave" cliff-hangers or series' hooks with one hand, so a final demotion, though this one smaller and more personal.
Hell, likely all the cons I wrote there are personal anyway. It likely is the perfect book for many people, and I might still read the rest. I'm just not in as much of a rush as I felt I'd be at the start.
