If you mean The Summoning. I read that a few weeks ago.........like you I love the Otherworld series. But I was not too keen on this one. It starts out well, but ended up feeling very much like I was reading about the school they have in the Xmen. I quickly got a bit bored and started skimming the last quarter of the book. It definitely has a young adult feel to it, much teen angst etc. Don;t get me wrong, the quality is still high, it may be that I'm just too old
. Don't get me wrong it is a decent read, not rubbish by any means, just not my taste, it wasn't deep enough if you get what I mean.
If you love Twilight you will probably enjoy this one, not because its the same story, but it has the same feel/atmosphere. I personally found Twilight had a definite young adult feel too...
