A Guy Like Him by Amanda Gambill

Skylar is the kind of girl who knows exactly how many seconds it takes to read this summary. She knows exactly what her perfect future looks like and how to get there because her dad has already defined it for her and her older sister has already paved the way.
That means she knows what college classes to take her junior year, what accounting firm she’ll work at after graduation, and exactly the kind of guy she needs to keep her parents happy.
So it’s only logical that she makes a pros and cons list after every coffee date. And when she unexpectedly dives headfirst into a casual fling, she defines it with a contract that clearly outlines the rules of this secret relationship.
In this coming-of-age novel — while she balances planning her sister’s wedding, going on way too many dates, and fulfilling obligations as SGA’s Social Outreach vice chair — Skylar has to find the line between perfection and what she really wants. And discover if they are the same thing or if it pays to sometimes break the rules.
