It's Boston, 1919, and the Cast Iron club is packed. On stage, hemopaths-those afflicted with the ability to create illusions through art-captivate their audience. Corinne and Ada have been best friends ever since infamous gangster Johnny Dervish recruited them into his circle. By night they perform for Johnny's crowds, and by day they con Boston's elite. When a job goes wrong and Ada is imprisoned, she realises how precarious their position is. After she escapes, two of the Cast Iron's hires are shot and Johnny disappears. With the law closing in, Corinne and Ada are forced to hunt for answers, even as betrayal faces them at every turn. An ideal next read for fans of Libba Bray's The Diviners.
