About the Author
CJ Acevedo has lived all over the state of California, Central, South, North and finally landing back somewhere in the middle. She married the boy she fell for when she was only eleven years old and together they have two beautiful heathens. CJ obviously loves to read and write. She can watch the Giant’s play baseball but hates football. She bakes when she’s sad, runs when she’s mad and dances when she’s happy (even if she cant find a rhythm to save her life). If you’re looking for her and can’t seem to find her, look on the staircase, it’s her favorite spot to read.
Without Doubt is the 2nd in the Without Series, but I'm guessing you don't need to read them in order as I didn't read the first (but will be adding that to my TBR right now) and I am not feeling at all lost. And after reading the book blurb for Without Boundaries, I see different characters so it looks like my assessment might be correct and you don't need to read them in order.
