"I've invited four of the (book's) interviewees to tell their stories and answer the questions of the audience. We will have a German, a Zimbabwean, a Turk and an American. You will hear a variety of voices and experiences," says O'Neill. "It was a great pleasure to write the book and meet the interviewees. Joint Publishing asked for a range of nationalities and professions to show the diversity of the foreign population in Hong Kong. After the closure for three years, it's very important to welcome visitors from all countries, including authors."

How well the Book Fair holds up under pressure is something only time can tell, but as bookshops vanish from retail spaces, it may turn into a must-do for book-lovers - though the expansion of Taiwan bookshop and lifestyle brand Eslite suggests book buyers will have at least one place to buy beyond the fair. (Eslite could not be reached for comment.) For now, the HKBF remains a key date for avid readers, parents and teens. "Overall, the Hong Kong Book Fair offers a unique opportunity to discover new books and engage in cultural events, and cultivates a greater appreciation for reading and cultural exchange," concludes the HKTDC spokesperson. "The fair is a family-friendly event, at which children can discover the world via books."
