Loulie al-Nazari is the Midnight Merchant: a criminal who, with the help of her jinn bodyguard, hunts and sells illegal magic. When she saves the life of a cowardly prince, she draws the attention of his powerful father, the sultan, who blackmails her into finding an ancient lamp. With no choice but to obey or be executed, Loulie journeys with the sultan's oldest son to find the artefact. Aided by her bodyguard, who has secrets of his own, they must survive ghoul attacks, outwit a vengeful jinn queen and confront a malicious killer from Loulie's past. And, in a world where story is reality and illusion is truth, Loulie will discover that everything - her enemy, her magic, even her own past - is not what it seems, and she must decide who she will become in this new reality.
