One Night Only is a fun premise about how you never think you'll see your one night stand again, but then the world ends up being a lot smaller than you expect. Sarah and Declan end up meeting at a bar, sleeping together and then going their separate ways, just shortly before Sarah's friend's wedding. When Sarah arrives at the venue in a rural town in Ireland, she comes face to face with Declan, but now as the brother of the groom. Cue a series of meet-cutes, more heavy flirting, and secrets that come out about both of their pasts. Would their fateful meeting be enough to start a relationship or would it end there? 
Walsh does her very best to write new takes on existing rom-com tropes and to keep the reader on their toes. I think she developed realistic character flaws, made their interactions interesting and fiery, and filled out the supporting cast really successfully. The narrator did a fantastic job, with excellent Irish accents and distinct voices. I would definitely recommend this to any romance and rom-com lovers, as the characters were funny, when placed into tricky situations and in dialogue, but genuine and sweet when around each other and it made me swoon.
