Lara recommends A boy and his dog at the end of the world by C.A. Fletcher

I didn't expect to be anxiety sweating from a book that rarely has more than two characters on the page at the same time, but this story had my heart pounding nonstop. Fletcher's writing fast tracks your attachment to Griz, the main character, and each moment of his struggle in this well-imagined post-apocalyptic world wrenches your heart into your gut. A quick read, but one that will stick in your head for a long time.
Publisher's description:
The world used to be crowded before all the people went away, but Griz and his parents were never lonely on their remote island. They had each other and their dogs. Then the thief came. There may be no laws left, but if someone steals your dog, you can expect someone to come after you, because what's the point of love if you're not loyal.
