Темная Башня. Путеводитель

Vincent's book delves into the series' themes and influence, but I'm curious what motivated him to frame it as a 'road' to understanding King's magnum opus. Was there a particular aspect of the series that resonated most with him?

The way the series ties into Stephen King's universe is fascinating, but I kept wondering if I missed some subtle references or if the author intentionally layered these details to deepen the lore.

For someone unfamiliar with the Dark Tower, would this book serve as a helpful guide or might it reveal spoilers that diminish the reading experience? Longtime fans might see different things than newcomers.
