It’s a very long time since a book has gripped me as much as this one. There was a time, close to the end, when it was genuinely hard to put down. I was so invested in the characters and their future happiness (or not!) that I didn’t want to leave them.

The setting on the Argyll coast is atmospheric and incredibly well drawn, as is the way of life but now and in the Viking age. Christina is the mistress of the Viking romance and personally I preferred the ghostly dual timeline story to time travel, which although popular I struggle a little to buy into.

For me, a sign of a great dual timeline is when I enjoy both stories equally and it was certainly the case with Hidden in the Mists. In the Viking era Asta’s world collapses when her father dies and her cousin steals her birth right and takes over the settlement, but help – and love – come from an unexpected quarter. In the present day narrative Skye is struggling to keep together the modern crofting existence she loves following her husband’s departure but then Rafe arrives out of the blue. Although the attraction between them is electric, both have secrets. And they’re both seeing ghosts.

The only other thing I’m going to say about this book is please do read it. Few writers pull off ghostliness as effectively as Christina and, coupled with an evocative setting, richly rounded characters, and a cracking plot, it’s one of the best romance novels I’ve read this year.

Given she writes ghosts so well, I asked Christina if she has ever encountered one:

“No, I have never had the honour of meeting/seeing a ghost myself, but I know people who have. People I trust implicitly, and who I’m sure would not lie about something like that or make things up. I used to spend a lot of time with friends in a 600-year old manor house which was definitely haunted. You felt it the moment you stepped inside – there was a certain atmosphere, as if the house itself was watching you and waiting for something. The owners told me all about their various experiences with their resident ghost. It changed my perception of ghosts as theirs seemed to be mischievous rather than trying to scare them. He (it was a man, dressed in chainmail the few times they saw him), used to sabotage all sorts of modern machinery, as if he didn’t like such newfangled things in his house – the lawnmower was forever breaking down, as were all the electrical appliances. It was hilarious, although obviously a bit of a pain for the poor owners who had to keep having things fixed or replaced. He would also open and close doors so that you’d think someone was arriving when there was no one there, or walk around upstairs when everyone was downstairs. At the time, I was actually terrified of possibly meeting him, but I’m braver these days and now I’m sorry I didn’t get to see him. I really do feel it would have been an honour!

“No one likes to think that death is final, that there is nothing else afterwards but a black void. The possibility that we can live on in some form or other is comforting, and with the amount of people who have come across ghosts, it is clear that there are plenty of unexplained things in the world. Therefore, I prefer to believe they exist, although I do think someone would have to have a very strong reason for lingering and it won’t happen to everyone. As for how I write about them, I just try to imagine how I would like my ghostly encounters to be if I had a choice and what possible reason they had for hanging around.”
