What Happened Before
After the loss of her mother and Chesca, Wyn is grieving and is trying to drown her sorrow by taking sparklies. Of course, drugs are no solution and she eventually needs to face her grief. In the process, she kind of manages to kill herself and ends up in the Library of Lives again, where she discovers that her father is still alive.
To save Wyn (and prevent the Palace from collapsing), Beira expends all her magical energy and ends up bedridden and sickly. This means Wyn now has to step into her mother’s shoes and rule the Realm. In between her Royal duties, she takes fighting lessons with Thor and has some fun s*x with her Guardians (chapter 5, if you want some steaminess).
It turns out that Ada and her men have disappeared together with the dragon shifter who poisoned Wyn. In another unexpected development, the Spring Goddess Flora turns up and becomes Wyn’s ally in return for protection from Angus.
A fake Crispin (a clone created by the Morrigan) invades the Palace and almost manages to kill Wyn, but gets stopped in time and ends up in the dungeons, where Arc interrogates him. The prisoner tells them about Castle Tioram, a place in Scotland where the Morrigan has created a Gate that leads to the Demon Realm. Assuming that Wyn’s Father is being held there, Frost, Storm and Arc head to Tioram.
When they’re in danger, Wyn suddenly finds herself merge with her magic and becomes what she was always meant to be: a Goddess. She manages to help her Guardians and free her father, but now new challenges are up ahead...
