Harlequin Mills & Boon has created 'The Chatsfield,' a transmedia story world based on a series of novels set in a luxury hotel, which incorporates social media for fan engagement and allows audience interaction through multiple platforms. Alison Norrington, the project's creative director, has developed a web series and integrated characters that relay their relationships in ways that resonate with fans, particularly leveraging dating site interactions. The initiative aims to build a robust audience rather than merely market books, focusing on immersive storytelling and community building.
