There are some multi-chapter AUs that span whole seasons, like the Lustra Verse (http://lustraverse.livejournal.com/511.html) and fanspired's The Song Remains the Same Verse (http://fanspired.livejournal.com/1394.html), also Diana_Lucifera& tersichore's Brother's Blood, Father's Gun (http://diana-lucifera.livejournal.com) series. Not quite what you asked for but maybe it will interest you since I've never seen any novelizations like that online.

The Bright Lights of Disturbia by Leonidaslion tells season one from a quite different perspective, but doesn't change much of what actually happened in the show. Highly recommended but warnings apply.
