I've read just over a dozen of Georgette Heyer's novels now but even though I now consider her as being one of my favourite writers I tend to find her books a bit hit-and-miss. There have been certain books by Heyer that I've found utterly charming and delightful (Venetia, Cotillion, The Talisman Ring) but then there have been other books by her that I've found downright tedious (An Infamous Army, Friday's Child).
For me Sylvester falls somewhere in the middle. I had mixed feelings about this one because even though it was still a fairly enjoyable read I found its pacing rather slow and draggy at times and there were even some occasions when the book made me feel a little uneasy. Phoebe and Sylvester have some really intense and bitter arguments in this book which actually made me feel a little bit uncomfortable. But there were still things that I enjoyed about Sylvester. It is well-written and I did really like the snowy winter setting and some of its characters. I especially liked Phoebe's friend Tom Orde (who reminded me a little of Freddy from Cotillion) and Sylvester's amusing and adorable little nephew Edmund :)
Rating: a 3/5 for the story itself but I'd give an extra star to the abridged audiobook version read by Richard Armitage. I listened to that audiobook earlier in the year and I actually preferred it to the unabridged paperback. The abridgement improves the story's pacing and Armitage is a wonderful narrator.
