Solasta Academy: Vicious Thorns

It is a new year at Solasta Academy, and Calia Nox has adjusted to her classes and newfound magic as a sea nymph. The night before the first day back, she and Arzhel Koen explore the hidden Kingdom of Neera in Doris Cove. Before they can go any further, they are attacked by an unknown assailant in the woods. They thought nothing of it until Calia realizes she isn't healing, and her infamous guardian tells her there has been a string of attacks with the same bite marks as hers.

Monsters will tumble out of the darkness. Secrets will be unleashed. Betrayals will drown her.
She is the last living Nox, and this is her fight for survival.
