text: Rob: Hey, yesterday at the party we talked about sci-fi books and you mentioned some awesome series you were reading
  Bob: Yeah, The Expanse. What about it?
  Rob: Nothing, I was just browsing the kindle store and couldn't remember the name :)
  Bob: Cool :) Just remember that it has like 9 books now - make sure to start from the first one, otherwise it's super hard to follow :)
  Rob: Thanks, will do that!
target: Bob recommended the sci-fi books The Expanse and Rob is interested in reading them.
