Spirit of the Spell. Witching World, #5.5

Some things are worth dying for. Others are worth living for again. When Damien dies, Oliana is devastated. It's understandable, he is her first love. She'll cry and grieve and, eventually, she'll move on, as she must-at least, that's what an ordinary girl would do. But Oliana isn't ordinary. She's a witch. And she isn't going to accept Damien's death without a fight. With the power of the four elements at her disposal, she can do more than challenge death.
The question is, what is she willing to sacrifice to get him back? * Spirit of the Spell is the prequel novella in the Witching World, a complete series of six full-length novels and one prequel novella, with non-stop adventure, empowered heroines, moody magicians, mythical creatures with attitude, and prickly castles with a mission. These books are young adult historical fantasy and are suitable for all ages.
Each book ends in a cliffhanger, but the series finale wraps up in an uplifting happily-ever-after.* The suggested reading order for the Witching World series is the following: Magic Awakens The Five-Petal Knot The Merqueen The Ginger Cat The Scarlet Dragon Spirit of the Spell - prequel novella Mermagic
