Plum Lucky Janet Evanovich

Hilarious as usual. Love the characters. And the wacky plots.
This happened "two days ago, on Saint Patricks Day. Grandma found a bag of money. She bought an RV and hired Randy Briggs to drive her to Atlantic City. Turns out the money belonged to this little guy who thinks he's a leprechaun. And the leprechaun stole the money from Delvina. So Delvina kidnapped the leprechaun's horse and grandma until he gets his money. Problem is, we only have some of his money."
