If you don't normally think of yourself as a science fiction reader, you might want to give Hayley Gelfuso's novel The Book of Lost Hours (#1,350) a try. The action begins when Lisavet Levy's father, a watchmaker, puts her inside the mysterious time space to save her from the Nazis on Kristallnacht. She never sees him again. She grows up mostly alone, learning about the books on the walls of shelves in this place. But it isn't totally safe; she sees uniformed men searching the shelves and destroying certain books.
Years go by until Lisavet meets Ernest, a young American, and falls in love. Book is their story as they deal with the consequences of destroying or preserving memories. Lisavet is eventually forced back into the outside world by a brutal and powerful American agent working for a secret government program. Given a new identity, she meets Ernest again but must keep life-changing knowledge from him. It's a difficult dance.
There are some interesting ideas here about the space/time continuum. Could it work like this? An intriguing premise.
