I'm very much looking forward to this one too.
It appears Jenna's got the plot and timeline of this whole sequel blocked out and based on Somebody New I completely trust she has an engaging story to tell with momentum, direction and a point to it, - one that develops the J/E relationship further and makes us love her J&E even more. I'm very curious to see where she takes this, as I don't think the end of SN immediately lent itself to a novel-length sequel, but much rather to little disconnected "short-story" glimpses, separate scenes in their new life. Of course Jenna will prove how limited my imagination is!
