Fated Mates
Fated Mates was originally published as a PNR series by Zoe Winters (Kitty's quirky PNR alter ego). It is now republished and co-branded under the main author brand (Kitty), using the other name to cue readers to the fact that it is NOT the normal "dark romance" fare they are used to from this author.
Future quirky PNR (paranormal romance) and any other lighter type of romance may in future be published under both names in order to communicate to readers what they are getting.
