In advance of their St. Patrick’s Day wedding, Tara Meehan and Danny O’Donnell are off to the Aran Islands with their bridesmaids and groomsmen for a joint hen and stag party. The weekend kicks off with the ferry trip to Inis Mór, as the passengers enjoy boozy milkshakes on board and entertainment from a pair of famous Irish-dancing twin brothers. But faster than Tara can say “Oh, Danny Boy,” a murder shamrocks the boat as someone’s spiked shake turns out to be their final round. Stuck in a rural island cottage, while a storm rages outside, Tara must find the Celtic killer before her luck runs out . . . St. Patrick’s Day is drawing near in Arborville, New Jersey and the folks at Hyler's Luncheonette are getting into the holiday spirit with a new, limited-time, Irish-themed menu item—a festive green milkshake appropriately named, “The Leprechaun.” It’s a hit, until a patron is felled by one of the frothy concoctions during a sheep parade through the town. Now, it’s up to Pamela Paterson and her Knit & Nibble knitting club pal, Bettina Fraser, to catch a murderer and put a stop to the sheer madness . . . Spring in Santaland means two things: the elves have more leisure time and iceball season is in full swing! To celebrate, April Claus’s friend, Claire, whips up some minty milkshakes for her bustling ice cream shop, Santaland Scoop. But when the St. Paddy’s promotion makes one elf the target of a decidedly unlucky strike, Mrs. Claus and her friends must figure out if the attack was a failed hit job, a crime of passion, or an extremely unfortunate accident . . .
