Goddess among the best (4)
I believe the answer is:
hebe
'goddess' is the definition.
(Greek goddess)
'among the best' is the wordplay.
'among' says the answer is hidden in the clue.
'HEBE' is hidden in the letters of 'the best'.
(Other definitions for hebe that I've seen before include "Cup-bearer of the gods and NZ plant" , "Daughter of Zeus and Hera" , "Youth personified" , "Greek goddess of youth, wife of Hercules" , "Herculean bride" .)
