Please do label YA books as YA books, first of all, so I know to keep away: but I promised to review it so i had to try and plow through. I failed, but I almost finished it: but I am probably not the right person to appreciate it.
This might go well with teenagers, the characters are after all teenagers to start with, and while they are supposed to be 24 later in the book, they do still act and think as teenagers. A young person might also overlook the stereotypes and so on, not because they are stupid, I don't mean that, but because they have not had the time to read so many books yet: for example the ensemble cast, consisting of a suspiciously well-sourced cast from different backgrounds, the Orphan, the Boy from a Happy but Poor Family, the Rich Boy and the Country Boy, for example. They meet on a train on their way to a wizard school - no sorry, wrong book, these meet in a coach on their way to a sort of magic school. Then there is an attack by highwaymen (that serves no plot purpose except there always is one in fantasy, whenever people travel by coach).
So, good news first, the book is decently edited, amusingly a hotel receptionist seems to have several heads which she nods, but there are very few typos and the language is fluent, especially the dialogue. Thankfully the cover has been changed for the Kindle, the original as I can still see here, has an amateurish painting in it, while otherwise it is OK. The two-tone tree reflects the themes of the book symbolically, rather than be a direct representation. The setting is a bit thinly realised, but it is still good to have fantasy not set in mock-medieval land, this is more like 18th century, with gunpowder and the trappings of civilisation. The names are also good, Bray, Yarrow, Arlow etc, not the overly curly names some people insist on foisting on fantasy characters.
The bad news is that besides the woefully immature and fairly one-dimensional (I have read worse, but a little flat anyhow) protagonists, the plotting is not done too well. There are logical inconsistencies with the way things are described, it is hard not to spoil it so cannot give too exact examples, but why for example did the writer write in a disabled character, only to sort of write him out again? There are none too many of them in YA literature... I imagine, as I said I do not read it. In fantasy too. The characters are given sort of superabilities, which vary from a genuinely super-superpower to meh, to something on the other hand failry useless and potentially a horrible, horrible tragedy - and no-one points this out? When the plot finally gets going, some of the plans the supposedly now professional characters do are just so poorly planned it's - no spoilers, remember?
So after about 85% percent in I decided sod this, I promised a review, this will have to do.
