Hanna Keller and her family run Maggie's Tea House, an establishment heavily influenced by the family's Hungarian descent and specializing in a European-style traditional tea service. But truthfully, one of the shop's largest draws is Hanna's eccentric grandmother, who's known for her remarkable ability to read the future in the leaves at the bottom of their customers' cups. Lately, however, her readings have become alarmingly ominous... Hanna is also an avid teacup collector and especially takes pride in the Anna Weatherley butterfly cup she recently procured. But the exquisite piece of porcelain soon becomes the center of a murder investigation, when it's suspected of delivering poison to one of the guests at their most recent event. Hanna's determined to find the true killer, exonerate her family, their business, and in the process, reclaim her beautiful Budapest Butterfly.
