Joanna, a Fleet Street journalist, chances upon the journal of the mysterious Anna Leigh. She is moved by Anna’s compelling confessional about her life-changing encounter with Julian of Norwich - an extraordinary woman from another age, who risked death at the stake to write a secret manuscript revealing the truth entrusted to her.

Joanna becomes captivated by Julian, remembering her own neglected ambition to pursue the truth at all costs. But Julian is from an alien world - can Joanna believe her promise that pain and suffering can lead to peace and happiness? Anna has the answer, but Joanna can find no trace of her.

Joanna’s conscience is tested and she is put in danger when confronted by a terrible choice. Does she save her career by smearing a whistle-blower who has exposed a government scandal in which her lover may be implicated? Dare she risk all she holds dear to capture the greatest treasure of all?
