"Ravishing in Red" by Madeline Hunter

This book is the first in the Rarest Blooms series, which revolves around four female friends who share a home with a large greenhouse in Regency England.  Audrianna is trying to clear her dead father's name when she accidentally meets Lord Summerhays, one of his persecutors, as they are both trying to confront a mysterious man who may know the truth about the scandal that led to her father's death.  An accidental shooting and rumors ensue causing them to join together to solve the mystery of how worthless gunpowder found its way to the front lines of a recent war, a war which left Summerhays' older brother unable to walk.
