Retrieval is a quiet novel. You will get more from the book if you take your time with the book, I think.
Nina remains in the passage because she didn’t use her ability to tell whether a soul is going to heaven or hell in life. The two men who loved her and protected her in life remain with her. There’s a scene in which an unspoken romance rule (given that this is not an erotic romance) is broken, which does a wonderful job of showing Nina’s past.
Same goes for Roman.
I hope that this will be the first book in a series.
