Found in two T-Rex of the key pesonnages Codex same author. Despite some difficulties in the beginning to really get into the story, I liked the turn that took the story. Indeed it took me a few weeks to get to the 200th page (reading intermittently), it only takes me two days to finish the book. As often, Preston managed to teach us things while entertaining us (here some notions about paleontology and details about the "lifestyle" T-Rex). Another book that we would see well suited to the movies!
