Rock Bottom

The Sisterhood, a group of women whose vigilante work has made them famous, has spent years making sure wrongdoers face consequences. A former classmate of one member begins to suspect that the foundation materials her firm supplies are causing bridges and buildings to collapse. Her suspicions pull the Sisterhood into the case. The company at the center of it, however, commands money, influence, and resources that can rival the group's own, and its leaders show no sign of backing down without a struggle.

Rock Bottom is part of Fern Michaels' Sisterhood series and features the same group of women and their collective approach to righting wrongs.
