Cryptic in its apparent straightforwardness, economical in its use of language but with tendencies towards abstraction and lyricism, inward-looking while (at least on the surface) dwelling more on the details than on broad psychological sweep, at once teasingly unresolved and, in the end, satisfyingly wrapped up, Let the Northern Lights... is a good example of a movement that increasingly seems to me to be constituting something of a seachange in current (pun unintended) literary fiction, both in the sense of exemplifying the style and in that of providing an example of how it can be done well.
It's hard to put one's finger on just what comprises or defines that 'movement' or seachange or whatever; I've picked out a few authors who seem to fit within it before - Scarlett Thomas, David Mitchell (?), maybe Ali Smith, Steven Hall (on the strength of The Raw Shark Texts, Nicole Krauss - but, apart from being relatively well-to-do 'western' writers probably sharing a broadly similar cultural background, writing novels which are usually in contemporary settings and kinda modernist in sensibility even if they're often laden with postmodern tropes and flourishes (I often feel that Murakami is a bit of a spiritual fore-runner), which in turn involves a certain preoccupation with phenomenology and perspective (and ideas), I'm not sure exactly what I feel they have in common. It's not that they're my favourite contemporary writers, even amongst those who've got their starts in the last 10-15 years or so (in which case Donna Tartt, say, would certainly be amongst their number, though it must be said that her work has a classic, out of time feel to me, and, to take an example from the opposite perspective, I was more frustrated by The Accidental than I actually liked it); nor are they particularly the most acclaimed/popular meeting that 'kicked off in the last 10-15 years' criterion (in which case see Jeffrey Eugenides, Zadie Smith, JSF, Dave Eggers, etc, etc).
Well, anyway, be all that as it may, I liked Let the Northern Lights... a lot, for all of the reasons I've already mentioned. Its rendition of Clarissa's journey of discovery through chilly Scandinavia has a lightness of touch and an elegance which sits pleasingly with the novel's more human aspects (though it errs at times on the side of being too terse, I feel). It's convincing - not necessarily in the sense of being realistic (though, incidentally, it more or less is) but more in the sense of being true.
