I loved the prequel, [b:Sing Me a Song|57678397|Sing Me a Song (Sacrificial Lambs, #0.5)|C.A. Rene|https://i.gr-assets.com/images/S/compressed.photo.goodreads.com/books/1617995565l/57678397._SY75_.jpg|90345998]Sing Me A Song, and up until the epilogue, I felt the same about Song of Tenebrae. Throughout the latter half of the book, I could feel it building to a cliffhanger and I was okay with that, but the epilogue felt like a pause more than a hanger and didn't leave me itching to read the next instalment. I will, of course, but I didn't get that feeling of urgency, of wanting to scream and shout and rail at the author because they'd left off like that. I feel no need to mark the release date in my calendar and pre-order to make sure I can get to it straight away, which is a shame because it really is a well-crafted world and mystery. Having heard from the author (in the comments below) I can understand why the story ends like this (it's making way for the next duo's tale) but it's not the ending I would've chosen.
Despite that, Song of Tenebrae is incredibly well written and it's amazing to see how Tempest and Raiden grow over the course of the story and how their relationship evolves. I really enjoyed the mystery side of things and want to hear more about Incognitus and their story. I'm curious to see where the story goes from here, but I'm just not itching to find out like I was before.
