I "read" this as an audiobook. An interesting time travel premise. Should a time traveler try to change the past for the greater good? What would the wider ramifications be? And what about the emotional connections the traveler would make in the past? Who gets hurt when the traveler goes back to the present? Kept my attention easily. Had it not been recommended by a friend (thanks Dave) I never would have read this Stephen King novel. Not typical Stephen King horror.
