Eric (A Surprise Baby Romance) by Jody Kaye

Some mistakes change the course of your future… Uncertain if leaving for college might mean losing the one person she’s come to count on, all it takes is a single misstep for Ginny to unravel both of their lives. Now the entire small town is convinced Ginny always intended on cashing in on her boyfriend, Eric’s, notoriety and snagging herself a Kingsbrier Quintuplet.
To make matters worse, Ginny’s stepfather is proving he’ll do anything to get his hands on Eric’s trust fund. With the help of his infamously misbehaved siblings, Eric sees Ginny is willing to do what it takes to earn his forgiveness… But a baby is a mistake you can’t take back.
