Starred review. In her sparkling debut, Johnson introduces vibrant and flawed Savannah heiress Keziah Montgomery, who comes of age as America hovers on the brink of the Civil War. Keziah, who should be a sought-after bride in aristocratic Savannah society, has epileptic seizures, a condition her family desperately tries to hide. Attending an abolitionist meeting with her childhood friend Micah Greyson, Keziah begins to understand how barbaric it is to own slaves and why they so desperately seek freedom. Despite Micahs warnings, Keziah finds purpose as a conductor for the Underground Railroad. After Keziahs brother is reported dead, Keziahs ailing father becomes even more determined to see Keziah married to a man who can financially take care of the Montgomery womenone whos not tainted by abolitionist ideals. Hiding a family secret of his own, Micah fears he cannot be the man Keziah needs. With more than a few twists and turns, Johnson crafts an inspirational tale of love, fortitude, and what it means to do the right thing when the very concept of right is challenged.
