Halcyon In Kaleidoscope features irregular and fragmentary writings - on ideas and values, places and people - which evolve over time into mini essais, paying humble homage to the peerless founder of the genre. The kaleidoscope is Halcyon's prime metaphor, viewing the world through ever-moving lenses.

A Mundane Comedy is Dom Kelleher's new book, which will be published in 2025. The introduction is available here and further extracts will appear on this site and on social media in the coming months.
