I've read all 6 of the Ghost Bird series and I held off on reading the Scarab Beetle series because I read somewhere that it gives a better glimpse of what the Academy is about.
So my question is if I read it will it be spoiling what's to come in the GB series?? Part of the draw in the GB books is still not knowing a whole lot about The academy and still being in the dark a little like sang.
But I do love crossovers!!! So I'm on the fence, should I read Thief and Liar? Also should they be read in a certain order in conjunction with the GB series?
