You should use NTFS Folder permission on the folders instead of share permissions. (set the share just use the NTFS folder permissions instead) Keeps things less complicated.
Right click on an applicable folder/select Properties/security tab. Remove applicable users and groups and then add the Author that will have permissions on the folder and files within.
You should add the Write permission and possibly the Modify permission (if you want them to be able to delete subfolders and files within their own folder) if needed.
Next, click the Advanced button and add a checkmark to Replace permission entries on all child objects etc..
Do the same for the other folders and corresponding Authors.
* Note
The steps outlined above in no guarantee 100% security over the authors folders and or files.. Meaning, I don't know exactly how IIS is setup, what access is available through the Net etc... or what else is going on. They are intended as a starting point which which you can modify as you see fit.
*Proactive
backup the Authors folders on a regular basis in case the server bombs or one of the Authors decides to bail and dumbs his/her folder. Or, better still, house these folders on a different server seperate from the web server.
