Night of the Dark Horse (An Allegra Fairweather Mystery)

Just another typical week in the life of a paranormal investigator.
I had barely arrived in Ireland to investigate a pooka terrorizing the villagers of Dingaleen when I got called to ride the fairy horse myself. When a pooka calls, you answer—and hold on for dear life.
Unfortunately, the beast tossed me into a bog. Fortunately, my gorgeous guardian angel fished me out. Just barely.
You see, Casper is still weak from tangling with an evil spirit on our last case. So he’s not even much help to me in the land o’ the green. The powers-that-be are even hinting at retirement…
But I won’t lose Casper. Not now. Not ever. As luck would have it, I have a chance, albeit a slim one, to save him and get the answers I need to solve the pooka case—if I just take a wee trip through Fairyland. Except angels aren’t welcome there, humans can’t eat, drink or sleep there, and time is running out.
