Yellow-Eyed Crocodiles

Josephine and Iris have always been different, like day and night, despite being sisters. Josephine is a quiet person, a medieval historian living a modest life with her husband and two daughters. Iris is an eccentric, femme fatale, moving in high society circles.
When tragedy strikes Josephine's family — her husband leaves her for another woman — Iris also decides to make radical changes. Lying to everyone that she is working on a historical novel about the Middle Ages, she convinces her sister to become her ghostwriter.
Now Josephine will have to juggle everything at once: her willful elder daughter, who blames her for her father's departure, paying off debts, working on the manuscript, and… new feelings?
