The Water Dancer

"Young Hiram Walker was born into bondage -- and lost his mother and all memory of her when he was a child -- but he is also gifted with a mysterious power. Hiram almost drowns when he crashes a carriage into a river, but is saved from the depths by a force he doesn't understand, a blue light that lifts him up and lands him a mile away. This strange brush with death forces a new urgency on Hiram's private rebellion. Spurred on by his improvised plantation family, Thena, his chosen mother, a woman of few words and many secrets, and Sophia, a young woman fighting her own war even as she and Hiram fall in love, he becomes determined to escape the only home he's ever known. So begins an unexpected journey into the covert war on slavery that takes Hiram from the corrupt grandeur of Virginia's proud plantations to desperate guerrilla cells in the wilderness, from the coffin of the deep South to dangerously utopic movements in the North.
