The Bloodmoon Tome

From publisher blurb:

A sorcerer who derived her power from her werewolf heritage, Mayan the Bloodmoon’s mastery of lunar magic and lycanthrope control were nearly legendary. Why such a bloodthirsty woman created a tome full of her most prized spells for later generations to study is a source of mystery, but lycanthrope and human spellcasters alike have sought the book out for centuries. The Bloodmoon Tome contains a dozen new spells along a lycanthropic theme.
