I’m a walking contradiction.
School principal who liberally drops the F bomb.
Fiercely independent yet willing to auction myself off for charity.
Serial monogamist who’s down for a no-strings one-night stand.

Except now I’ve gone from one-working-ovary to co-parent in the time it took a stick to turn blue.

F. Bomb.

Ian Donovan may be a richer-than-hell venture capitalist, but he’s no Prince Charming ready to sweep me off my feet. Good thing I don’t need him. I’ve been doing fine on my own for forty years, and I’m not about to start changing that now.

Ultrasounds, swollen feet, midnight cravings? Bring. It. On.

But why is it when you finally swear off men, you meet one who’s too sexy—and determined we can make it work?

F. Bomb.


“Great read that was funny, snarky, and completely entertaining.” -Bette H., Goodreads

“This book was exactly what I thought it would be: fast, fun, and fluffy.” -Jessica G., Goodreads

I adored this spin on a fairytale! First off, kudos to the author for creating characters of an older age - it adds even more reality to an already contemporary novel.” -Keshia M., Goodreads

I abso-freaking-lutely loved this one! Honestly, if this book is any indication (which I sincerely hope it is!) this line--Entangled's August imprint--is exactly what I've been looking for. I can't wait to read more from it, and (hopefully!) more non-YA reads from Ms. Hammerle too!” -Becky M., Goodreads

Get ready to laugh your butt off with Knocked-Up Cinderella, a chic-lit-ish contemporary romance. I smiled and laughed, and although there’s no sexplicity, their chemistry was amazing and they have some really steamy and downright hot scenes.” -Edgy Reviews

As someone who reads a lot of Romance, it can sometimes feel like a whole segment of the population is left out. We have YA books, New Age books, and our standard Contemporary Romance books chocked full of women worried about turning 30. There h

When I saw Julie Hammerle looking for reviews of her soon to be released seasoned romance (romance for the 40 and older set) Knocked-Up Cinderella it sounded like a story I’d really enjoy so I requested it and I’m so glad I did. Julie is a new to me author and this is her first adult romanc ...more

4/5; 4 stars; A-

This was a fun surprise. A contemporary romance with mature main characters, no manufactured drama, and a happy ending. The title wasn’t the greatest but that’s minor. This new to me author is someone I will keep an eye out for. ...more

Ughhhh this book was just so dang CUTE but also funny, snarky, and sexy!!

I immediately loved Ian and Erin as our main characters as well as their storyline. I also liked that they were in their early 40’s instead of the usual mid-20’s/early 30’s rom-com characters.

I had absolutely no problem readin ...more

Erin's gone from one crappy relationship to another. In her forties and ready to take her life back, she decides that a one-night stand is exactly what she needs to take her life back. She's ready to focus on herself and have fun. However, what she wasn't expecting was for that one night to lead to ...more

This was a really cute story. I love how strong And independent Erin was but that she still let herself feel vulnerable when it came to Ian. I even really liked Ian, though at times I wanted to smack him upside his head for being dense. I wouldn’t call this a slow burn since they got together ...more

It’s been a while since I have indulged in chick lit. I forgot how sugary and cute they can be. And predictable. Boy and girl meet, things go well, throw in some drama, kiss and make up, and TADA! HEA. Simple, predicable formula. It’s kind of like watching the Hallmark channel, just funnier. Don’t g ...more

title: catchy
cover: cute design

I flagged this at the library b/c the cover & title grabbed my attention. I wasn't sure what to expect as this is a new writer to me. (she's written YA books previously)
i wasn't disappointed.

This was exactly what I needed right now. A lovely, sweet, romantic story. I liked Ian and Erin a lot. I loved that they were both in their 40's (although, I have to admit, they acted very immature for their age sometimes and that annoyed me). Them falling in love was very nicely done and believable ...more

By Paige December 14, 2019

This was an absolutely adorable book. It doesn’t start out in the traditional way, where girl meets boy and they slowly build up to a relationship. No, they have a ridiculously hot one night stand and she winds up pregnant. What I love about Erin is that she’s no-nonsense and has a backbone. Ian is ...more

I abso-freaking-lutely loved this one!

I've read almost all (read: I missed one--how did that happen?) of Ms. Hammerle's YA books, so when I saw this title and her name with it, I got all grabby-handy. Seriously. I didn't even read the blurb.

By Maureen June 18, 2019

I rarely come across books with characters in their 40s. So when I read the blurb of a book by yet another author new to me, I did not hesitate in reading it.

What I liked most about this book is the “tone” that was set. From the very start, I could actually hear the characters’ voices in my head, in ...more

I picked this up because it was recommended as a fun book to read. It was fun. Considering the trope, it was light and made me smile. It’s not quite a romance but telling the story from alternating points of view helped to connect to characters and understand how they got where they were going. I fe ...more
