The Fill-In Boyfriend

By Kasie West

Book Overview

After getting dumped on prom night, perfect Gia enlists a "fill-in" boyfriend to save face, in this charming and sweet fake-dating rom-com from Kasie West, perfect for fans of Lynn Painter and Jenny Han.

?Gia Montgomery has a plan for everything.

Even when her boyfriend, Bradley, dumps her in the parking lot of her high school prom, Gia has the perfect pivot. This was supposed to be the night she proved to all her friends that he really existed. So all she has to do is find a cute guy to be her fill-in boyfriend--two hours, zero commitment.

But Gia didn't plan on spending the days after prom thinking more about Fake Bradley than her actual ex. To get this under control, she'll have to track her faux prom date down and repay the favor.

Gia is all too happy when he needs her to be his fill-in girlfriend--three hours, zero commitment--but suddenly, this fake relationship starts feeling all too real.

It was the perfect plan, but Gia didn't plan on falling for the fill-in.

Customer Reviews

“Very good”

Came like new

Great book!

This was a great book! Had really good messages like changing for the better, choosing good friends and being kind. It's cheesy and obvious, like Hallmark movies, but it was great! It was funny and heartwarming!

Fun Time

I really enjoyed this. I admit it's predictable and cheesy, but if you're just looking for a feel-good, cheesy rom-com type book, this is a great one to enjoy.

the fill in boyfriend is an amazing book.

I eish it could have never ended but I also wanted to see how everything would turn out.

Phenomenal

Literally every book I've ever read by Kasie West has blown me away. They're funny, emotional, well-written. They keep your attention. Fill in boyfriend is one of my favorites. You won't be disappointed.
