This is the 4th book I have read on The Morrigan, and I was completely disappointed. There is a lot of misinformation in here.
For example, The Morrigan is a complex Goddess, who has many aspects of Her, but she is not the Triple Goddess or Maiden/Mother/Crone.
I have also not read anything in the lore or myths that state She is a sex goddess.
I would check most of the content in this book and do your own research.
