Circle Of Days by Ken Follett [Paperback]

Set in prehistoric Britain thousands of years before recorded history, the novel follows Joia, a visionary young priestess who dreams of uniting the warring tribes of the Great Plain through the construction of a monumental stone circle—a structure that will eventually become Stonehenge.

Together with Seft, a gifted miner and engineer, Joia dedicates her life to turning this seemingly impossible vision into reality. However, their dream unfolds against a backdrop of severe drought, resource scarcity, political rivalries, and growing distrust among farmers, herders, and woodland tribes.

As violence erupts and tribal conflicts threaten to destroy any hope of cooperation, Joia and Seft must navigate war, ambition, love, sacrifice, and survival while striving to create a monument that could unite generations and outlast them all.

The story imagines how one of humanity's most famous prehistoric monuments might have been conceived and built, blending archaeological speculation with epic human drama.
