High Dive by Jonathan Lee
I liked this multi-POV book about an IRA attempt to assassinate Margaret Thatcher. I suspect it survived the feeling of cliche inherent in showing both sides like that by being very spare in telling you what it means, and by leaving plenty of tendrils that aren’t tied up neatly. (The diving motif, for example). And by giving us not just hotel worker and terrorist, but a father and daughter, with the terrorist who lives with his mother.
