The Black Dogs of Glaslyn

Nothing has been the same in The Prince's household since he traded one of his fine hunting dogs for a strange, green-jacketed monkey, and now his Kingdom, in Medieval Gwynedd, is starting to suffer. One thousand years later, in modern day Beddgelert, Martyn Llewellyn is struggling to recover from a traumatic childhood and has been offered the chance to make a name for himself at Bangor University through conducting an experiment on dogs. The lives of Martyn, The Prince, and The Prince's son are inextricably linked: haunted by their own demons, their own 'Black Dogs', each has to find a way to survive.

Guy Holmes' first book, The Cadet Story, was published in the 1980s. He subsequently had a career in the Health Service in the UK, working as a clinical psychologist for over 25 years in community settings with people with severe mental health difficulties, people who heard voices, were suicidally depressed, and frequently hospitalised. During this time, he published over 50 academic articles and three highly successful books: This is Madness, This is Madness Too and Psychology in the Real World. He retired on the grounds of mental ill health in 2015. He is the grandson of renowned Welsh author Frank Richards, whose most famous book, Old Soldiers Never Die, is still in print nearly 100 years after it was first published.
