The Day After Never - Nathan Van Coops
Satisfying end to the series, but... I'd love to have more. I love these characters and the story is woven together so well. I loved the exploration of the possibility of paradoxes and watching the relationships develop. I've already passed these on to several friends. Such a great trilogy! Fun!

Honestly, Nathan, you have to revisit Ben and his friend some day. I miss them and they have so many stories to tell!
