Angel

Angels are also called the 'Sons of God' and serve as the bulk of Heaven's forces in the eternal struggle between good and evil.

There are several different types: Archangel, ordinary angels & Guardian angels,

However the books don't give much information about the differences between them aside for the fact that Guardians are lesser immortals, mortals that rose to angel status due to their good nature and deeds.

But in Succubus Heat, during a line of questioning, Georgina asks an Arch-Demon about his angel counterpart, referring to her as the local Archangel, which makes it relatively safe to assume that Archangels in the books mirror their 'real life' legends and stand as the strongest of Heavens forces and that they stand as direct opposites as the Arch-Demon's of Hell.

Some noted Angels include:
 * Carter (Archangel)
 * Lucinda (Guardian Angel)
 * Yasmine
 * Joel
 * Whitney
 * Isabelle
