Seventeen centuries ago, three sisters set the course of their people after the brutal murder of the Elder Alpha at the hand of the Faoladh. With the combined force of all three elder clans, the sisters destroyed the Faoladh's physical being, but without the help of their mother, the Lunar Wolf, they were unable to eradicate his spirit, and though he has not been seen since, his presence is felt throughout every forest and haunts the Conroicht that protect them. Six months before their Sealing Day, Saoirse and Moira Conall wake to discover they've been Sealed too soon, a rare - and deadly - occurrence that has only happened once before since the creation of the Conroicht. As their mother, Alpha of the Ròisìn Clan, and the Council of Elders frantically struggle to make sense of it all, the twins prepare to face the biggest decision of their lives: almost certain death, or forfeiting their birthright and losing their status and abilities as Conroicht. The only two heirs of an uncontested Alpha line, Saoirse and Moira risk destroying a seventeen century old pure Alpha line if neither of them can complete their first Transfiguration, but the next full moon is a lunar eclipse, which makes it nearly impossible for new wolves to complete their first Transfiguration. As the girls prepare, Saoirse begins having visions of an ancient darkness that threatens the lives of every living Conroicht, and an unseemly ally makes his way into her life. With threats at every side and demise seeming to shadow their lives, will the sisters be able to overcome the daunting tasks that lay before them?

To the outside world, Nicole is a bit of an enigma: solitary but well liked, smart but erratic, and shy despite her interesting beauty. She's lived through more than the average person her age, and her tormented mind and shaky relationships reflect that fact to her almost daily. In a particularly low point in her life, her therapist recommends she starts writing out every part of her life that she can remember, but that means facing the one thing she's avoided most of her life: the unabridged truth. As she nears her 25th birthday, memories of her life begin to coalesce. Riddled with uncertainty, plagued by grief and haunted by her past decisions, she makes the frightening decision to dive into every feeling causing her to question what she really wants for the rest of her days.
