I read pretty much anything, from fantasy (City of Stairs by Robert Jackson Bennett) to romance (Bared to You by Sylvia Day) to classics (Heart of Darkness by Joseph Conrad). The only genres I don't read are self-help and comic books/graphic novels.
For the first two thirds of the book I found this really quite slow and a bit of a struggle to stick with (the only reason I was able to keep going was the fact that it was only a couple of hundred pages long and I felt that I would be giving up too easily if I couldn't finish a book that short). The last third of the book was quite a bit better and more interesting. I intend to read more of Peter Ackroyd's books so I hope that this book is not a sign of things to come or the best of them all.
