Irish Magic by Susan B. James

What do you do when everything goes wrong?
Make a wish on a four-leaf clover, right?
There’s no other logical way out of it!
But a clover wish is a heart wish. Everyone knows that.
When part leprechaun Bradley Flynn is charged with finding Kate’s true love, he calls on retired matchmaker Essie O’Callaghan who happens to have a mission of her own.
Dr. Michael Walshe had a ring in his pocket when he walked in on his girlfriend sleeping with her costar. He wants no part of Essie’s plan to find him a wife.
Fate—or something more leprechaun-shaped—has Kate and the doctor both heading to Cluhalaugh, home to Ireland’s most famous matchmaking festival. And somehow their paths keep crossing. The more they see of each other the harder it is to resist exploring their reluctant attraction.
Will Kate realize that Michael could be far more than the cure to her writer’s block?
