Four years after her destined mate publicly rejected her, wolfless healer Elena Vance is summoned back to Silvercrest Pack. The pack that cast her out is being slaughtered by rogues — and the dormant Moon Priestess blood in her veins may be the only thing that can save it. Alpha Kael Donovan rejected Elena to save her life. Now he must beg for the help of the woman whose heart he destroyed. She gives him thirty days, a price, and no forgiveness. But every day back in Silvercrest wakes a power someone in the pack wants her dead for — before the next full moon decides whether their bond lives again, or she walks away forever.
