In Winter's Shadow is the final book in a trilogy of fantasy novels written by Gillian Bradshaw.

Though the traditional punishment is death, Arthur exiles them instead, Bedwyr to his native Less Britain, Gwynhwyfar back to her clan.

When days go by without word of Arthur, Gwynhwyfar becomes a nun in a northern abbey run by a friend, eventually becoming its head.

While civilization and learning ebb among the Britons, monks from Ireland arrive and build a monastery on a little island called Iona, working to accumulate and preserve knowledge.

Kirkus Reviews considered the novel to be subpar, stating "this weepily enervating effort doesn't fulfill the mild promise of Hawk of May (1980) and Kingdom of Summer (1981).

[1] However, the Historical Novel Society reviewer disagreed: "Though there are certainly elements of fantasy in Bradshaw’s retelling of this familiar tale, realism reigns supreme.

... Full of longing, betrayal, intrigue, and reconciliation, Gwynhwyfar’s tale is a rich, rewarding read.
