For three lifelong best friends, a college graduation trip to Ireland is supposed to be their last hurrah before starting their jobs, and taking on the stresses and responsibilities of adult life. Heather, Tiffany, and Amanda are on a mission to turn the Emerald Isle upside down...or at least wreak a little havoc, drink a wee bit too much, and kiss hunky Irish boys...before returning to their hometown of Chicago.

When Rhiannon, a powerful fairy, pays a surprise visit to their adorable, thatched-roof rental cottage in County Clare, and persuades them to sign one-year Love Pixie contracts, their lives are drastically altered. Newly armed with fantastical superpowers, charmed necklaces, and the ability to turn ordinary substances into enchanted pixie dust, the girls join together to fight "love crime" and help assigned couples on the brink of disaster build bridges back to happiness. It all sounds quite exciting, until they realize that learning how to use powerful magic is not only time consuming, overwhelming, and confusing - it’s not easy to hide from their family, co-workers, and most importantly - potential love interests.

To complicate matters even more, the trio is repeatedly tempted by the fairy’s rebellious sister, Aideen, who challenges them to break the rules. Perhaps if they listen to the "bad fairy" they can finish their assignment quicker...and get back to work...and play...before anyone is the wiser.

However, the girls were raised to know that there are consequences to bad behavior - at least in the non-magical world. Afraid to ask if there is such a thing as magical jail, the two more sensible Pixies hope to rein in their most wayward partner - before their contracts are terminated...and their couple’s relationship implodes into a pile of ordinary dust.
