WHITE RIOT, Joe Thomas
SMALL MERCIES, Dennis Lehane
BLACK RIVER, Nilanjana Roy
THE END OF US, Olivia Kiernan
YELLOWFACE, R. F. Kuang
TELL ME WHAT I AM, Una Mannion
THE SECRET HOURS, Mick Herron

To get this list, I listened to a podcast (16 minutes) on RTE Radio 1. Very informative. Declan sold me on BLACK RIVER, a debut mystery by Nilanjana Roy. Just ordered it.
Declan Burke used to publish his best of the year list in the Irish Times, which has a paywall. I was glad to have a chance to get this list by listening to an excellent podcast instead.
