Global Transient Amnesia (TGA) in The Day After the Party is the medical diagnosis Katelyn receives after losing all memory of her birthday party. This condition is typically triggered by extreme stress or traumatic events, causing temporary memory loss of recent experiences while leaving other cognitive functions intact. The diagnosis becomes central to the mystery, as Katelyn must determine whether the stress came from something someone did to her or something she herself did.

The Day After the Party centers on three main characters: Katelyn, the protagonist celebrating her 36th birthday; her husband Aaron (also called Toby), who lies about the party events; and Leah, Katelyn's best friend since age six. The story alternates between Katelyn and Leah's perspectives, revealing their thirty-year friendship from childhood through marriage. Both Aaron and Leah are portrayed as selfish and deceptive characters hiding crucial information from Katelyn.

The mystery of what happened at Katelyn's birthday party is the central plot of The Day After the Party.

The truth involves secrets, betrayal, and jealousy that slowly emerge as Katelyn's memories return.

Katelyn and Leah have been inseparable best friends since they were six years old in primary school, maintaining their bond through high school, university, relationships, and marriage.
