Embracing Her Ever After by Brenna Jacobs

What is Tessa supposed to do when an old flame and a surprise new baby turn up on the same day?
Brilliant engineer Tessa Fuller has the opportunity of a lifetime at work, and all she needs to change the world is a little help from her old college friend, Ethan Bedford.
Ethan can give her five weeks before he’s off to chase his own dreams, and when they meet again for the first time in six years, Tessa realizes the gawky guy she graduated with has grown into a super hot tech genius.
Just as she’s on the verge of a fun, short-term fling to discover once and for all what-might-have-been, her wayward sister drops a baby on her doorstep and disappears, leaving Tessa to take care of the kid.
One huge problem: Tessa doesn’t know a thing about babies. And she doesn’t have time to learn while the clock is running out on her dream project at work.
But Tessa’s team is determined to show her that she’s not alone, and while they might be clueless about babies, they know a thing or two about engineering. As their baby “hacks” and inventions get progressively wilder, Tessa is less and less sure she really can have it all. And the first thing she has to give up is Ethan.
Except Ethan isn’t a quitter. And he’s not about to give up on Tessa, not when the flame that flickered between them in college gets fanned back to life.
Can a team of hilarious engineers, one sweet baby, and a handsome blast from her past open Tessa’s heart to new love and second chances?
