i haven’t read the first series yet but i know they are both mixed together so google the reading order and it will tell you the recommended order!!
and for the off campus and briar u series which i loved you read the first five of the off campus books and then read the four of the briar u series, those ones don’t mix together! hope that helps!!
To read the addicted calloway sisters is better if you do it like this: addicted to you, ricochet, addicted for now, kiss the sky, hothouse flower, thrive, addicted after all, fuel the fire, long way down and some kind of perfect. These books can be read separately but it won’t make as much sense since they start where the other one left off even tho is three different couples
