I really loved this book and cannot recommend it highly enough.
I've read and enjoyed most of this author's books ranging from literary fantasy to space opera yarns but this one really stands head and shoulders above the rest.
Finding Helen starts with a nostalgic epiphany and doesn't look back as it explores one man's attempt to reconnect with a past life snatched abruptly from him. The prose is fluid, the plot engaging, the characters are drawn with an emotional depth both real and startling and the 60's culture described is refreshingly free from stereotype. What's so impressive is that the author combines a riveting and page-turning plot with such vivid characterisation in a way that is so rarely encountered.
Read this with a soundtrack of Anne Briggs, Shirley Collins and Sandy Denny.
