Pendragon Series

I started a new series called Pendragon, even though I only have read a few chapters the book is really exciting. It's very descriptive and "shows, doesn't tell". Everytime I end a chapter it leaves me off at a very dramatic part and moves on to another world! I guess it could be called a cliffhanger. The main character's name is Bobby Pendragon. His uncle takes him to a dark subway at night on the most important day of his life. He disappears through a door with a staron it and gets pulled into another world. The portal is called a flume. He lands at the tip of a mountain followed by his Uncle Press. As they sleigh down the mountain they are attacked by hostile animals called quigs. All quigs are different, it depends on their territory. The last page I read was that Bobby's uncle got dragged away by knights and Bobby fainted on the snowy ground.
