what should I read next?

I guess it depends on what 당신 like.

I'm going to read both since I own them, but I can't decide

Read Rampant first for 2 reasons. 1) I have no idea what it means so it sounds exciting and 2) it just sounds 더 많이 exciting, immortal gives everything away!!

Immortal was good. Not the best book ever but still good
