All good things must come to an end. Even the women of the Sisterhood--the stalwart sorority that has helped to right so many wrongs--have been content to let their gold shields gather a little dust while they enjoy friends, family, and the comforts of civilian life. But the group's leaders, Myra Rutledge and her best friend Annie de Silva, remain as vital and feisty as ever. So when a string of anonymous emails arrives at Pinewood, suggesting shady dealings at a local assisted-living facility, the two immediately set out to investigate. Emanuel Macklin, the financial wizard behind the sprawling, high-end senior complex, has amassed a private fortune that would make Fort Knox look like spare change. But the hefty returns Macklin promises his investors may be garnered at others' expense. In fact, Macklin's entire enterprise is one enormous Ponzi scheme that's about to collapse--taking the life-savings of thousands of innocents with it. Myra and Annie know this is a mission tailor-made for their brand of justice, but they'll need to enlist some new and untested allies. And even as they set out to foil one of their most cunning adversaries to date, Myra faces a personal challenge that will rock the Sisterhood to the core.
