Books I've Half-read and Then Forgotten About

I have a terrible habit of reading 40-60% of a book and then, even if I'm really enjoying the story, dropping it for a shiny new book. These are their stories.
  1. Yes Please by Amy Poehler
  2. The Bostonians by Henry James
  3. The Signature of All Things by Elizabeth Gilbert
  4. The Fran lebowitz reader by Fran herself
  5. The book of strange new things by Michael Faber
  6. The Paris Wife
  7. The Return of the King by JRR Tolkien
