Author Barbara Erskine will launch her new book, Sleeper’s Castle, at an invitation-only event on Tuesday June 28, in the most appropriate of settings, Hay Castle in Hay-on-Wye.
The novel is set in the tumultuous Welsh-English borders of the 15th century.
This year marks the 30th anniversary of Ms Erskine’s first novel, the bestselling Lady of Hay, a historical novel about Matilda de Braose who built Hay Castle.
Lady of Hay has been translated into 29 languages over the years, has sold three million copies and is still in print.
The popularity of the book has likely brought hundreds, if not thousands, of visitors to Hay from all over the world.
Barbara Erskine said: "Hay Castle has haunted me for most of my writing life. This return to the castle will be a most exciting, almost surreal occasion for me.
"It is the perfect place to celebrate my first novel, which tells of the building of the castle and my latest, which describes it under attack and for me and my readers to raise a glass to the ghost of Matilda, the real Lady of Hay.’
Ms Erskine has recently moved to Hay-on-Wye.
