DOUBLE THE FUN

There appear to be two tie-in novels on the New York Times Hardcover Fiction best-seller list for 10/7/07.

Jonathan's Story (by Julia London and I) at #7, a tie-in to the daytime soap, Guiding Light; and Dexter in the Dark at #11, a tie-in to the returning cable drama, Dexter.

If you want to stretch a point, you can even consider #9, Bones to Ashes a sort of tie-in, though, in this case, the forensic book series predates the TV series, Bones.
