Shadowmarch (Shadowmarch Trilogy Book 1) Tad Williams
King Olin of Southmarch has been kidnapped and when his son Kendrick is murdered the two youngest children the twins Briony and Barrick are made co-regents in a court were they have no idea who to trust. To make things worse the Twilight people fairy folk from behind the Shadowline to the north are preparing for war.

I really did not like this book and had to struggle through it. That majority of the characters seem complete idiots the only likeable character was Briony. The story jumped about a lot and seemed to be going nowhere for most of the book.
