Speed bumper cars

I got back into Book 2 today (which may have a new working title), and though I got a revival of inspiration I also ended up with a new issue… I can get some forward momentum, but I have to create more conflict to keep the pace good and keep it from getting boring.
But how?
I’ve got a few things in mind for speed bumps on Clare’s story, but I have several things to consider. Is it going to work for the overall arc of the series? Is it going to muck things up? Am I going to be getting in too deep?
Only time will tell. Time and beta readers lol
