Complete Book of Amber by Roger Zelazny

Yes, this is a classic oldie and it's huge at 1264 pages - but let me tell you, it helps to have all the books in one place so you can keep track of what you've read. It opens with Corwin waking up in a hospital and realizing a) he had partial amnesia, b) someone had deliberately put him in hospital and kept him there, and c) he has the energy and will to change all this.

Corwin, we discover, is part of a royal family trying to kill each other off. They also have special talents like being able to call each other through a deck of cards, walk a mandala-like Pattern that's a source of their power, and travel through parallel universes. They also have a dad who may or may not be dead.
