Dual Destruction by Kate Hawthorne is a high-stakes, dark enemies-to-lovers romance. It's the first book in the Duality series and is known for its intense, suspenseful plot where two characters are able to kill each other but choose not to.
Foster is a hitman tasked with killing Sage, but after a chance encounter leaves Sage bleeding in an alley, Foster chooses to nurse his target back to health instead.
It is often recommended to read the free prequel short story, Dual Hostilities , to better understand the backstory and tension between the two leads.
