Intricate threads of destiny all woven together, tying several people to each other over the course of hundreds of years and multiple reincarnations. There's an aspect of Groundhog Day (you're stuck repeating this until you get it right) that is somehow very satisfying. It's a compelling, easy read, with characters that are three-dimensional and human and believable. The elements of predestination and prophecy add an intriguing layer to the story, keeping you guessing whether and how each person will fulfill their Wyrd. I love how the same souls tend to reveal their essential characters from one lifetime to the next, while still being completely different people.
