S.T. Abby is a dark romance series by Penelope Sky, following Abby, a woman on a quiet mission of revenge against the men who destroyed her family, and Levi Donoghue, the FBI agent hunting the vigilante he doesn’t yet know is her. The audiobook format does something print can’t quite replicate here: the dual narration pulls you between two people keeping secrets, and the tension lands differently when you hear it.

If you like your romance with real stakes and morally complicated leads, this is the series for you. Abby is not a passive character waiting to be saved, and Levi is not a simple villain or hero. The slow unraveling of their dynamic across the series rewards listeners who stick with it, and the narrators make every charged silence feel earned.
