Today Hollywood Crush revealed the third book to Pittacus Lore's I Am Number Four series. The Rise Of Nine is set to be released sometime this summer! I've been meaning to read his series but I haven't yet, what do you guys think? Is the series worth reading? The cover doesn't seem to be as bold as the previous books but I don't think that's necessarily a bad thing :) So "I Am Number Four" bookworms, what's the verdict? Yay or Nay?
