Rapture is a talent in the Discipline tree, you will need to spend 18 points in Discipline to max it.
Larger mana pool means larger amount returned, so Blessing of Kings goes great with this. Prior to Patch 4.0.1 there was also a benefit from Mental Strength, which has since been removed.
Up to and at least through Patch 3.0.8 this ability appears to return mana based on the priest's target and not the priest making this ability mostly useless (except mildly helpful when heal/shield a paladin or feral druid).[1]
Patch 3.0.2 (2008-10-14): Added. Patch 3.0.8 (2009-01-20): NOT FIXED (see Bug section above) Rapture: This talent will now correctly return mana for Power Word: Shield based on the caster's mana poll instead of the target's mana pool.
