An interesting idea for a book. The ice caps are melting, sky cities are being built, but people aren't being let in
That's really the only good part I found in this book.
I kept reading, kept waiting for something interesting to happen, but I didn't get what I was waiting for. I got a bunch of things that didn't make sense.
The main character is rather peculiar. During the storms on her island, she shows absolutely no fear; the thunder and lightning and pouring rain has no effect on her. She just gets bored, aches to be outside. Though she's been living through storms her entire life, their should still be some hint of fear, since the storms seem to be almost mini hurricanes. Trees would be knocked down if there were any, houses knocked down if they weren't stone. Anyone caught out in a storm is as good as dead, yet she waits until the last minute to come inside. She's reckless like this throughout the entire book, wants to die multiple times.
During the storm, she uses her cyberwizz; technology that lets her essentially fly through the Weave, although her movement is simply and always described as 'wizzing'. The Weave is essentially a digitized web, all the information there for the taking, physical things made out of electricity for Mara to find and sift through. Somehow, monsters and ghosts are also created (cyberdogs attack her, and she's concerned about Weave ghosts, though still not particularly fearful). How she got the cyberwizz and how she's so simply perfect at it is never really explained.
Furthermore, she somehow falls through a bridge (though if she's 'wizzing' around, I don't see how that's possible) and then falls out of the Weave. There she meets a cyberfox.
Later on she convinced everyone to go to a sky city, almost drowns when her best friend and family die because she wants to die as well, is broken into the city by an orphan child (she describes him and the others as urchins), is found by Treenesters (curious people with different ways), wanders around their for awhile and learns of the Stone-telling (the Treenesters' prophecy that they will be saved one day if they basically just sit there). That's the entire first 3/4 of the book. She then breaks into the sky city, meets the Cyberfox in real life, falls in love with him over a couple hours, has him shut down the entire city, frees all of the slaves, Treenesters, and refugees waiting to get into the city that they've been refused entry to, and the book ends as they are on ships heading North. That's the insane, impossible ending of the book.
The entire thing isn't really plausible. There's no way no security in this awe-inspiring sky city didn't detect her. There's no way one simple virus shut down the entire city in a split second and kept it down for probably a good hour. There's simply no way the book is possible.
It was an interesting read, nonetheless. I was particularly enthralled by the Treenesters, though their origin isn't really delved into, except for Candelriggs, the leader. I can't tell if Gorbals is a young child or Mara's age; he seems to switch between the two. I can't tell if Broomielaw is Mara's age or a young woman; she does the same as Gorbals, as do many of the other Treenesters.
It generally was a great idea, but could have been executed much better. Less detail on the sky city, and getting to the climax before the last fourth of the book, just for starters.
