Ok, we just finished book 1 "The invasion". This is an original storyline that covers David returning. Jake is assaulted by David in his house, Marco and Sam go to the rescue. Get their arses kicked but manage to scape and know their rounding everyone up in the barn. Jake is throwing pebbles to Cassie´s room window (I´m assuming she´s there) so she opens and he can explain her what happened. Dru (the new original character) is in the barn with Ax. Sam is explaining all of the above to Rachel. And I don´t have idea were Tobias and Shaun (yet another original character) are.
