Xenobia Summary: Ciel awakens to his new life filled with questions that only his butler can answer for him.
Review: After the end of the Kuroshitsuji II anime, Ciel and Sebastian are both adjusting to Ciel's transformation and the changed terms of their contract. Ciel struggle to embrace his new life, clinging to the remnants of his humanity even while moving on from his identity as the Earl Phantomhive. For his part, Sebastian remains one hell of a butler, mentoring Ciel through his transition even as he wrestles with his own conflicted feelings for Ciel and for his changed role in their contract. Meanwhile, Will and Grell are trying to track down a dangerous supernatural killer, with some surprising help from the Undertaker.
"Eternity" is technically a sequel to an earlier Sebastian/Grell PWP. Although you don't need to read it to understand the story, the casual Sebastian/Grell relationship developed in the prequel does carry into the first part of "Eternity" -- much to the chagrin of Ciel and William. However, the main pairings in this story are definitely Sebastian/Ciel and William/Grell. For me, the slow-burn romance between Sebastian and Ciel is the highlight of this story. As Ciel physically matures, he finds himself dealing with a newfound attraction to his butler, leading to all sorts of adorably awkward UST. I appreciate that Xenobia gives them the space to grow into their feelings for each other and the physical aspect of the relationship. I was also surprised at how much I enjoyed the plot with the shinigami. Undertaker is a gem in this story, and I loved watching him interact with Grell and William. The killer they are trying to track down also has an interesting backstory with a satisfying link to Undertaker's past.
While this story is not as polished as I'd usually prefer (the prose could use some tightening, and the plot loses some focus near the end), it's a good read nonetheless. I've enjoyed it a few times now, and definitely recommend it.
