Unfortunate Syren

  A syren lacking fortunes in her share
  Doled
out by Fate's specific Sisters three 
  Is cursed
with cursing's heavy weight and fare
  For nature is the
force compelling she.
  A cry to warn the sailors turn
their backs
  Enamors them with cryptic hoping
zeal
  By then already bound to mortal
cast
  To be the ones brought to Poseidon's heel.
