In this Arcane Society novel set in Victorian England, Leona Hewitt, a gifted crystal worker, isn't the only one sneaking into Lord Delbridge's private museum to recover a relic. Thaddeus Ware, a mesmerist with psychic gifts, is on a similar mission. Neither one of them has any idea that this relic--a rare ancient crystal--will lead them in a deadly chase where danger and desire await.
