I usually don‘t like a story within a story, but I really liked this one. The letters from Leo really ramped things up a bit (though there were times I took a minute to unscramble things in my head, as we had Freddie, a character in Hannah‘s book, using real life events to write her own book. But Leo was reading and commenting on Hannah‘s book!). I still thought the letters worked well and it brought an added tension. Cont in comments...
