We used to have a contrib module that could accomplish this [1]. 
(without the need to directly edit the db)  Perhaps we should update and 
revive it.

In the meantime, you'll need to add entries to your "book" table with a 
nid matching that of the node you are converting to the book type.  You 
can set parent and weight to 0 (and leave "log" empty) then modify them 
from within Drupal if you'd like.
