SOLVED. Sci-Fi/Fantasy (possibly YA) series with human cloning, action-pack, and 4 main characters? [s]

I remember when I was younger almost a decade ago (sometime 2012-2014) I read a fantasy book series (there were at least 2 books) with 4 main characters (2 girls, 2 guys) probably YA(?) and the plot had something to do with clones? If I remember correctly the books were pretty action-filled, lot of getting chased and hiding, and the characters couldn’t tell who was real because of the cloning or programming or something like that. I think one of the characters in one of the books was called Olive? There should also be a character called Rhys. The character development in the books was not very good, focus was more on the plot/action. I got the books from a library and remember the first one’s cover to be blue (not sure what else is on it, I just remember it being blue lol). I’m trying to make a list of all the books I’ve ever read so finding this one would be great!!

From the reviews this might be the book that you're looking for! They mention both the names you remember, it was published in 2012 and the first book's cover is blue:
False Memory by Dan Krokos
