not bad as entertainment reading: characters are passably believable, story is ok, the idea of technomagic is quite interesting and fresh, asks for exploration. the one thing that drove me mad though is the obvious neglect to the writing quality; example:

bla, bla — says protagonist.
bla, bla, bla — says someone else.
bla, bla — says protagonist.
bla — says antagonist.

etc, etc. that «says» is the most used word throughout the book, it's maddening.
