Can anyone tell me the ending of The Ice Twins? Might contain spoilers.

I've started reading The Ice Twins and I'm not really sure it's for me, (I'm far too easily creeped out and I also can't really be bothered), but
I'd like to know the twist/ending.
Anyone?!

Not telling the ending, such as it is, because that is unfair on accidental viewers. But if you toss the book aside now - or, better, hurl it with considerable force - you aren't missing anything.
Pretty crap. imo.

Well I was hoping the title would warn people... Maybe I'll try to skim read it.
