Right. But all I wanted to confirm is that the book implies that ALL traffic is suspended until the OSPF network is converged?

The BDR already has adjacencies with all other routers on the segment and has been keeping tabs on the DR such that it can take over rather gracefully. A BDR election is then subsequently held to backfill the BDR position. No adjacencies should be torn down during this process, though new ones may be created between the set of non DR/BDR routers and the new BDR. Hope that helps.
