The Hugo Award for Best Series (2017-2021)
The Hugo Awards category for Best Series is still fairly new, but every year there is a lot to read.
I've included all the volumes in these series up to 2021, even if they hadn't been published when the series was a Hugo Award finalist. Some of them keep getting nominated, so it's good to keep up with them. :)
