I love it when authors do this! It's like a cherry on top of the sundae, gravy on top of mashed potatoes, cheese on top of broccoli...(must be hungry with all the food references!) Bonus, Bonus, Bonus! 
 We get to find out the back story of Tod becoming a reaper. And honestly, this is my favorite cover of the series. I really don't care for the others. 
 If I wasn't a Tod fan after My Soul to Keep, I definitely am now!
