The Gatekeeper's Fate

A complete adult urban fantasy trilogy. 

Once, Holly Lynn was the Winter Gatekeeper, wielder of the powerful magic of the Unseelie Court. Now, she's shunned by humans and faeries alike… until a series of murders committed by a dark fae draws her back into their realm again. 

The Gatekeeper's Fate takes place a few months after the Gatekeeper's Trials trilogy. ​If you want to avoid spoilers, I'd recommend reading the other Gatekeepers books first.
