Kamila Shamsie, Home Fire

One of my absolute favourites. A retelling of Antigone set in modern Great Britain about three siblings - a set of twins and their older sister - whose father was a jihadist. I found the classic themes of Antigone - struggles with family, duty, sacrifice - really well updated to reflect more contemporary struggles with identity, faith, as well as political issues like immigration and the toll it can take to be pulled into two different directions: tradition/modernity, fitting in/staying connected to your roots, conforming/preserving some form of inherited cultural identity.

And yes, you obviously know how the story ends from the start, but the ending is still so heartwrenching. As we know from Fleabag, the greatest love stories are still between siblings ("the only person i'd run through an airport for is you" and such).
