Eternally Yours is a fitting title for the close to the Immortal Beloved series that chronicles live-for-the-moment party-girl Nastasya's growth into a caring, committed, community-minded, 450-year-old young woman. Nas' maturation at the hands of immortal organic farm/commune rehabber River has not compromised her sarcastic, self-deprecating sense of humor, and the erratic steamy romance with Viking Reyn will keep readers turning pages. New threats to Nas' safety emerge as her true heritage is learned, endangering everyone at River's Edge as the final epic battle is waged. A fine conclusion to a popular and unique series.

Nastasya's journey from a viciously selfish existence to one centered in community spirit is completed in this conclusion to the Immortal Beloved trilogy. When the enclave at River's Edge is threatened by dark magic, Nastasya finds the self-confidence and love to fight for what she has come to believe in without losing the sarcastic, self-deprecating voice Tiernan's fans love.

The engaging final installment in the series that began with Immortal Beloved (2010) reveals new information about the world of the immortals and ties up loose ends. After running away with her manipulative ex-friend Innocencio against everyone's better judgment, recovering immortal socialite Nastasya has returned to the West Lowing, Mass., rehab center called River's Edge. Although Nastasya's narrative voice is still glib, prickly and often cynical, she has changed since the trilogy's beginning: "I was far gone enough to admit that, yes, I really did need help....more than I needed to be proud, or brave, or cool, or even just not gut-wrenchingly humiliated." River, the kindly and more-ancient-than-most immortal who runs River's Edge, never gives up on Nastasya, but as her less-trusting siblings begin to arrive from around the world, suspicion about Nastasya's intentions and behavior grows. Meanwhile, Nastasya and fellow immortal Reyn alternately kiss and fight; Nastasya starts a project to revitalize West Lowing's mostly abandoned downtown; and destructive Terävä immortals wage an international war to seize power. As usual, the story's most compelling aspect is Nastasya's emotional growth, aided by River's kind, patient and nonjudgmental tutelage. The sly, slangy narrative voice keeps the story moving, and flashbacks fill in some of the gaps around Nastasya's and other immortals' pasts. A satisfying series-ender. (Fantasy. 12-18)
