Lloyd McNeil's Last Ride by Will Leitch is a nice novel that starts with the main character, Lloyd, an Atlanta police officer with a thirteen-year-old son, Bishop, finding out he has just months to live.
Lloyd comes from a police family, with his father having been a tough as nails Major, but he's a beat cop focused on trying to help people through his job. As Atlanta citizens would would record with their phones he and other police at work, Lloyd would regularly assume the persona of Happycop, your friendly neighborhood officer.
After finding out about the brain tumor that would soon kill him, Lloyd worries about how to provide for Bishop after he's gone, and comes up with the idea to accomplish this by dying in the line of duty. The book both funny and a lovely story about family, legacy, and what people will do for one another.
Similar to two other novels from Leitch, How Lucky and The Time Has Come, it's a short book that's also memorable for the heart it has.
