I remember a great deal of publicity when Tides of war came out last year, the book itself didn't really interest me as it is a historical novel, but I've gritted my teeth and got on with it as it is on the Orange longlist.
It's a tale of two halves essentially, we learn about Harriet's life at home in Regency England interspersed with her husband James' life in Spanish fighting in the peninsular war. It's obviously well researched as there is enough detail to give one a good sense of life back then, always very much more important in a historical novel where the reader isn't necessarily au fait with the circumstances.
Whilst I enjoyed reading about Harriet's life in London, attending lectures at the Royal Instution and developing a fascination with chemistry, making friends and so on, and found her to be a likeable character, I was disinterested in the battle scenes and descriptions of the war.
If you like historical fiction, then do pick this up, I am sure that it is an excellent example of the genre. It is just that I don't.
