Series Names

I am currently Penulisan a series about two groups-Undesired Legacy and Disguised Angels. They are at war with one another, the beginning buku are building up to it and the last ones are going through with it. Undesired Legacy is a group of assassins who believe in choice even when it means war, destruction, etc. Disguised Bidadari believe in equality and peace. They want everyone to be the same and dependent on each other. The series is basically about these two groups going at it, so, what should I name the series?

(Just in case it helps, here are the titles of stories in the series)

I'm Paired With Whom?
We Were Dared
Honestly, I'm Lying
City Boys
Traitor
Black Hearts And Battle Scars
