Shamrocked by Joely Sue Burkhart

A gargoyle, a leprechaun, and a motorcycle gang walk into a bar…
Scratch that. A human woman (me) accidentally walks into a Faerie bar run by a leprechaun who keeps a cursed gargoyle on a shelf. Somehow, that gargoyle goes home with me, and I start dreaming of a man.
Doran. He’s trapped in stone and darkness, and only I can free him.
He says I’m the treasurekeeper, and I need to find his friends, the other treasures, so we can break his curse. He haunts me night and day, driving me to hurry. I can’t sleep. I can’t think. I have to find them. I have to free him.
Turns out his friends aren’t that hard to find, because they’re drawn to me, too. But these whiskey-drinking, tattoo-loving, motorcycle-riding badasses are resigned to their fate. Over the centuries, they’ve lost too many treasurekeepers to risk their hearts and souls again.
I have to find a way to convince them to join me. Before it’s too late.
