“Secret Baby for Dr Grump” is a very enjoyable easy going read that had me hooked from the first chapter! After a one night stand, Olivia’s life gets very complicated when she finds out that she is pregnant. After being unable to contact Luke, she makes the decision to raise Riley on her own.

After getting a job as a Medical Assistant in a private hospital, she packs up and moves to New York. On the first day, she meets the doctor she will be working for and is met by a pair of piercing blue eyes …. OMG it’s Luke! She has never forgotten that night and oh yeah, he is Riley’s dad. Mind you, he does not know that he is a dad.

They have one night of hot passion that leaves a lasting impact on both of them. Are they able they to turn off and ignore the sexual tension and wanting each other? The heat between Luke and Olivia is hot from the start 🔥Once I started reading, I could not put this book down! At times you will laugh, you will cry, get angry and frustrated - most of all, you will love the twists! This book will charm “the pants off you” and leave you going back for more 😊

A thoroughly enjoyable read from one chapter to the next - at times you are metaphorical “on the edge of your chair” wondering what will happen next. You will fall in love with Luke and Olivia, hoping that everything with work out for them and they have a future together. Overall, I would highly recommend this book and you will not be disappointed 😊

Dr Luke and Olivia (Liv) have, what they believed, was just one night of fun. It became so much more, and with neither seeing each other for seven years after that, seeing each other again, in the unlikely of places, reignites that moment in time. However, with their being a result of that night, Liv finds herself fighting with being Mum and protecting their child first, but also aware that Luke has a right to know.

I have always loved everything Ava has written, and I do believe that this one, to date, is my favourite. There is alot to love about our beloved Dr Grump, and as the book starts to unravel those layers, we see hurt, and we see that he too was affected greatly by that one night, and was left wondering and wanting more. Of course there is challenges with Dr Luke being the superior in this working dynamic with Liv as his medical assistant, but you simply cannot deny the overwhelming attraction, desire and need to establish a relationship with Liv, and first and foremost their daughter. Read in a day because I loved it so much. Thank you Ava, this was beautiful and I enjoyed it so much.

Luke and Olivia's Love Story

Dr. Luke Jennings is a top neurosurgeon at a major NYC hospital. He is also the CEO of a company that distributes specialized medical equipment that he patented. He is 45 years old and a billionaire.
He meets a beautiful young woman in a bar, and they hook up. He gives her his number, but he makes a mistake by a digit.
Olivia Davis is the young woman. She realizes that she is pregnant, but she can't reach him.
The book starts 7 years later. Olivia has been hired as a medical assistant. Of course, she was hired to work for Luke. They meet, but she acts remotely because she wants to hide their daughter. Luke eventually discovers that he has a daughter.
The doctor/assistant relationship was a problem from the beginning. Olivia is very competent, and Luke is a renowned surgeon, but their love affair, under that scenario, is meant for disaster.
The couple sneak around in the file room, having sex and date in public. Both love their daughter, but Olivia could have very easily transferred to another doctor to eliminate the conflict of interest.
The book is interesting and a good read.

Move over Greys Anatomy and ER combined because there is a new HOT neurosurgeon in town, and he is going to fill you up with EXCITMENT. When Olivia (Liv) and Luke meet at a bar their one night of HOT and STEAMY sex leads to some mixed emotions. Luke thinks Liv just up and left and Liv is upset because the phone number Luke gave her was to a restaurant. So, move up 7 years later and Liv is working at the same hospital Luke is but also as his assistant. So, in order to see if they can get back together again and if Liv will tell Luke he has a 6-year-old daughter with her is the question you want to read to find out. All I am going to say is don't plan on sleeping or doing anything constructive until the book is finished with. :) Look at the cover if that doesn't SCREAM HOTNESS then I don't know what to say to excite you.

Loved the way this story began and the heat was all the way through this book.🔥

Olivia and Luke - one night stand. Their connection is more than that and they both know it. One incorrect phone digit made a significant difference in what could have happened.

Fast forward six years - Olivia moves away from her support system for a new job as a medical assistant for Dr. Jennings. Dr. Jennings = Luke😳

Ground rules, let not talk about our past. Sounds like a plan but that attraction of six years ago is not going anywhere.

Olivia has a huge secret. Dr. Jennings is off-limits and the complete opposite of the man she was with six years ago.

How their relationship unfolds is well worth the read. Hot, hot, hot! Loved the story!

Ava never disappoints!.

Hospital romance

Another brilliant slow-build romance from Ava Nichols; with great attraction, chemistry and spice between the main characters, misunderstanding, tension, humor, a twist and a 6-year-old you can't help but love.

Olivia has a great one-night stand with someone she thinks she'll never see again. But seven years later she finds herself working as the man's new medical assistant. She tries to keep her distance but still feels the attraction.

When Luke sees Olivia again he can't believe it as she had never got in contact after their night together; though now he's her boss he can't act on his feelings for her, which are definitely still there. But when he finds out about her 6-year-old reminder of their night together can he find a way to bring their family together?.

Another great book from Ava! A delicious one night stand, a misunderstanding with a number and a life long reminder of what happened. This book kicks off with plenty of steam and makes you want to find more. Luke and Olivia are destined to meet again but this time he is her boss and not in a position to make a move on her even when he wants to.

When they try to resist the pull between them, they ramp up the tension until it snaps and then phew! Feel the heat between them coming off the pages. A great storyline with all the feels in it. There are some laugh out loud pages and others that will want you to weep.

A definite recommend.

OMG Mind blowing to a one night stand of passion. It was a steamy page turner and the suspense was captivating of romance. I was on the edge of my seat and I couldn't even put it down. Olivia and Luke chemistry and physical attraction was sensation of passion and rekindle old feelings again. As they gave into their urge to fight the temptation any longer as they had fun and laughter and romance. There were many secrets that she was hiding from him and this one was very big. Finding love again is going to be hard with a child on the way.
Now after reading this book and you won't be disappointed. I received advance copy of this book via Bookfunnel and am voluntarily leaving my honest review. Trina Jones

One night stand, happily ever after.

You start out feeling so bad for Olivia being left with a life-changing surprise after her 1 night stand, although it's obvious from the memories that it was a mutually pleasurable affair and no regrets.

Fate intervenes and you quickly realize that said 1-night was a product of miscommunication where Luke & Olivia could have had more all along. At least they can't keep their hands off each other now.

The way they look after and support each other, Luke with liv's art, and Liv to the point of losing her job, are true relationship goals. Their HEA was hard fought and well earned. Super cute couple!

Get ready to smile and laugh over the antics of Dr Grump, aka Luke. When he has a new medical assistant thrust upon him against his wishes he isn’t prepared for the shock of his life! When Olivia is presented to the Dr that she will be working with she’s not prepared for her past to come back and bite her in the behind but Oh Boy does it ever!!! Fighting bureaucracy, overwhelming chemistry and even jealousy has twists and turns in this story that you will not expect. A great read that will keep you entertained until the last page.

I found this book very addictive and a very enjoyable read. Thanks! I thought the mixture of developing romance against personal history worked well to give a great storyline. I loved the heated interplay between Luke and Liv! The ache to have a relationship with his newly discovered child and the pure love he has for her that we see from Luke is also heartwarming... awww!

I think this book should appeal to a wide audience - Ava Nichols has done it again, drawing us into a story which you don't ever want to end, but at the same time want to find the happy ever after!.

Wow, What a great book, It won’t take you long to get drawn into the drama between Olivia and Luke. From their amazing one night stand to the time they are reunited seven years later. Chemistry that’s explosive, wrong numbers and life-changing surprises. This book is an emotional page turner that is hard to put down. The characters are well-developed and likable. The story line has twists, surprises and an amazing HEA. I received a free copy of this book via the author and I am voluntarily leaving a review.

This is a second chance, off limits romance between medical assistant Olivia and her boss, neurosurgeon Luke, who had a one night stand seven years ago. These flawed but likeable characters and the unique plot make for an entertaining read. Once they reconnect, it is a bumpy ride with drama and steam, sexual tension and chemistry, twists and turns, plus appealing secondary characters to keep the reader interested. An engaging page turner.

This was a great second chance, secret baby romance.

Luke and Olivia have a steamy one night stand, though it wasn't intended to be a one and done. A wrong number causes all kinds of issues.

Fast 7 years, and they meet again as boss/employee. The connection is still there, but how will things work out when he learns he's a father? Will they make it as a family?

Great read. Lots of emotions, loads of steam, and tons of heart. Highly recommend.

Another brilliant read from this author, the characters are always well created and the story pulls you in so you don't want to put it down.
There's small bits of drama, some steamy love scenes, lots of romance and a cute 6 year old who keeps them both on their toes, I definitely laughed out loud at some parts!
A brilliant read with a HEA.

Secret Baby For Dr. Grump by Ava Nichols-- awesome story, coincidence happened when Olivia8 gets a job at a hospital, where her one night stand works. This story is full of drama, attraction, and lots of chemistry. Luke is confident in what he wants, and whom, yet there are outsiders who are trying to ruin what they have. Absolutely beautiful family/ story.

Olivia's Secret

A revelation is made years later when Olivia and Luke are reunited through their careers. Nosy colleagues and sexual tension really add to the drama that unfolds in this story. Can Dr. Grumpy find his sunshine despite the misunderstandings of their past? This was a fun read.

Great story!

Luke is a neurosurgeon, a very well known one. Olivia is a hard working medical assistant. When she got this job she didn’t realize that she was working for Luke. She had a secret that she kept from him for seven years. He was a father. When he found out, he wanted to be in Riley’s life. There are many hills to climb to try and be a family.

The chemistry between these two is strong when they first meet. When they end up working together years later, they can’t easily act on those feelings, but the connection is still there. Add her daughter and the story continues to get more interesting. This story is well written and fun to read. I recommend this book.
