Both of the stories included here fit the above description. The lead characters, especially the vampires, are conflicted about their desires and choices and how those will affect others. The author does not shy away from talk of God, angels, damnation, etc., and it makes for a much more interesting read that the usual stuff. One reviewer in the book called the ending of Forever & the Night "bittersweet." I worried about that through the whole book, only to find it inaccurate. Pay no attention.
Miller's vampire world is gloriously detailed, with a well thought out history, compelling and well-defined characters in both lead and supporting roles, and just enough doubt as to the outcome to retain reader interest. I look forward to seeing them all again, especially Valerian. Superior writing.
The only thing I have against these stories is that Miller tends to wrap things up too quickly, leaving the resolution not quite realistic. Also, I really would have liked to know more about Aidan & Maeve's no-longer-existant sibling relationship. These two things drop the work to 4.5 stars.
