Whispers of the Wolf's Pact

Isolde, the second princess of Eldwyn, is reborn on the day she's meant to choose her servant beast. In her past life, she put her trust in Lucian, the eight-tailed spirit cat — only to be betrayed and killed by him and her older sister, Seraphina. The only one who avenged her was Kael, a Moon Wolf, who brought his entire clan to war for her sake.
