This is another one of Krentz's book from her Arcane Society series. Grace and Luther make a great team. Krentz's theories on paranormal theories are well-planned and consistent. I like the fact that she keeps introducing new paranormal senses. I think we have the possibility (capabilities?) of having some paranormal senses and have to agree with what she writes in the book that we it's perhaps not because we don't have the capabilities but that we don't use or are not aware of those capabilities. The one thing that I'm disappointed about is the fact that Krentz seems to give her woman heroine strength and power but in reality never seems to be always bowing to a male hero. That the women's role is to supplement the man's more powerful paranormal sense or to his vast experience. She often calls the women assistants rather than having the men as the assistant. This series is consistent and for it to cross time and have stories in the past, present and future is a different twist. If you like to read about paranormal experiences and like a little romance this would be a series you would enjoy.
