The Myth Seeker by Cory Barclay

A banshee who just wants to sing.
A leprechaun with a gambling problem.
A sex-addicted succubus in recovery.
Vampires who want a sunny day at the beach.
And then there’s Steve, the regular joe who inadvertently brought these flawed mythical beings to our world. But he has no idea how he did it, which is a problem, because it’s his job to bring them home.
All this responsibility is putting a serious damper on Steve’s directionless lifestyle. Then he finds out a dark force is trying to kill him and his friends. And he might be falling in love with one of his charges…
Steve realizes he must get his act together, before it’s too late…
