i've already read City of Bones and i know that city of ashes is suivant but i was wondering if i would be confused if i read city of glass before i read city of ashes, cause i recieved city of glass first and i don't know what i should do.

I think toi should read "City of Ashes" first than "City of Glass". It is the seconde book and there are things in that book which are vital to "City of Glass". So if toi read "City of Glass" first than you'd be confused as to how that happen ou how toi got there. It would feel like, toi missed a whole chuck of the story. The livres continue on with each other.

toi have to read them in order! City of Ashes might not be my fav of the series but it's sooo important, I didn't get that until I'd read them about three times but it is really vital to the series that toi read it first. So much happens, so much changes...Read them in order

Read them in order it will have the same effect if toi read the last one instead of lire the 2nd book first trust me i have read the series 3 times and i still read them in order. Hope toi like them!

Don't read them out of order because a lot happens in the seconde book that is referenced in the third, and it would get confusing. Plus, if toi already know how the series ends, then CoA will be less intense and toi won't get the full effect.

I think you'd get confused. There's a lot of vital information in CoA that's expanded upon and mentioned in CoG.
