The Green Hills of Snowdonia Books in Order

The Green Hills of Snowdonia is a two-book adventure set in Wales, with the mountains and coastline of Snowdonia providing more than just a pretty backdrop. The landscape shapes the mood: misty hills, old stories, and the feeling that the past is close enough to touch.

The series begins with From Across the Ancient Waters, which opens with sudden danger and pulls the characters into a mystery that feels both personal and historical. From there the story widens into questions about identity and what, exactly, is worth chasing.

Legend and longing sit side by side.

In The Treasure of the Celtic Triangle, the search becomes more explicit, with clues and lore pointing toward a fabled treasure connected to Welsh history. But Phillips doesn’t let the hunt stay purely external. The books keep circling back to the idea that people can spend their whole lives chasing the wrong kind of reward, and that the truest riches might look a lot like courage, humility, and love.

The tone blends suspense with a reflective, faith-aware undercurrent. You’ll get strong atmosphere, a sense of discovery, and characters who have to decide whether they’re willing to change, not just win.

Read these in order, starting with From Across the Ancient Waters. The second book lands better when you’ve walked the ground with the characters and felt how Wales itself becomes part of the story.
