Now the Crone has taken dozens of staff members, visitors—even children—hostage at the British Museum, demanding that Morgan turn over the staff. Willing to kill, possessor of powers beyond anything ARKANE has yet encountered, the Crone seems unstoppable. Morgan’s only advantages are her wit, her skill… and Blake Daniel (of the best-selling Brooke and Daniel crime thriller series).
