I've been seeing this book/series around for a while now, often popping up in Amazon's "customers' who bought this book also bought" recommendations. I finally succumbed and bought Spider's Bite. Unfortunately, I was right. It wasn't for me.
Strong characters, lots of action, impressive world building and some sexual tension - but I couldn't get past the level of violence.
It's funny. GA Aiken's Dragon series is violent, but I adjusted to that. Perhaps because it's tempered with humour and love and family.
Spider's Bite was just too strong for me. But if you're not freaked by a bit of blood and revenge, I can see why this series has its committed fans.
