Trying to remember a tween/middle school book series about twin sisters

I don’t remember too much about the series other than the sisters’ names were Reese and O’Ryan (randomly able to remember this because my friend and I argued whether Reese was pronounced like Reese Witherspoon or like a Reese’s cup). The series had chapters that would flip between their perspectives and it mainly just centered around their family, friends, etc. just usual middle school life and drama!

ETA: this would have been around 2008-2011ish time period!
