The second part of this Book is called "Fixed light". A pretty interesting title since "fixed" could either mean "repaired" or "stationery"/" unmoving". I have no idea which it is beforehand.

@AkaBobHoward That's great to hear!

I can see why people aren't a fan of them, they're not the most straight forward books out there. I put the series down after the first book the first time, but decided to pick it up again after seeing Hello Future Me talk about it. Not regretting it!
