Iridescence is the name for the UK’s next Eastercon. It will be at the Hilton Birmingham Metropole Hotel, 3-6 April 2026.

Eastercon is the UK’s longest-running Science Fiction convention. It mostly focuses on literature and book-related matters, but not exclusively. Its Guests of Honour include RJ Barker, Emma Newman and Karen Lord, who are all well-regarded, award-winning science fiction and fantasy authors.

You can register to attend the event by going to their website Eastercon2026.org .

Its Guests of Honour include P. Djeli Clark, LR Lam and Tamsin Muir. More details can be found on easterconglasgow.org
