I love being pushed out of my comfort zone.
There have been some brilliant and very successful standalone books that work in themselves and also seem to refresh a series. Anyone who writes a series lives in fear of it becoming stale, so you do whatever you can to keep it fresh – although it does feel a bit nerve-racking to write outside of your comfort zone.
I think when you get people who are really talented and you take them out of their comfort zone, you get a lot more out of them.
