Wonderfully fun nanny/employer romance

This is a fun, well written, heartwarming and entertaining story. With a mile-high one night stand, nanny/employer romance, brilliant character chemistry, wonderful banter, twists, attraction, healing and found family, a nanny with a sunshine personality, billionaire single dad, an overly friendly golden retriever, a sweet little boy, romance and love.

When Addy is dumped in the airport before moving her life she thinks things just can't get better, but fate takes pity on her and she's upgraded to 1st class and ends up joining the mile-high club with the man in the seat next to her. Then finding herself in Chicago with no home, no job and no luck; she starts applying for nanny jobs and is shocked when she gets to one interview to find that it's with the man from the plane.

Ethan has a lot on his plate, still getting over the death of his wife and trying to raise his son. With his current nanny leaving sooner than expected he starts interviews, with Oliver's help, for a new one but Oliver doesn't take a liking to any of them, until a last minute extra interviewee arrives and both Oliver and Captain, their dog, like her. Ethan's problem is he likes her too, only she's the girl from the plane and he knows he shouldn't.

They settle into a routine and things are working well, with the pair growing closer and Oliver happy with the arrangement. But when Ethan's best friend comes to visit things become tense when he turns out to also be the man who ruined Addy's life.

Addy's new adventure turns into a nightmare when her now ex-fiancé decides that their relationship isn't working and leaves her at the airport devastated. Addy decides to go anyway which is where she connects with Ethan. Their banter on the plane leads to an intimate encounter, a one and done thinking she will never see him again so imagine her surprise when the nanny position that she applied to lands them together again. Ethan has a lot on his plate he is still coming to terms with his wife's death and all the drama surrounding it all while trying to raise his son. He wasn't looking for a relationship but Addy walks right in and falls right into place with his son making his life lighter. Close proximity has feels developing and when his best friend comes to visit it almost leads to war because he is none other than the man that ruined Addy's life at the airport. I loved this story from the hilarious banter and antics to the colorful characters that drew me into this story and had me hooked until the last page.

Triplet Babies for My Ex’s Best Friend by Summer James is a fun, heartwarming romance that perfectly blends humor, emotion, and sizzling chemistry. Addy and Ethan’s story is packed with laugh-out-loud banter, sweet family moments, and just the right amount of drama to keep the pages flying.
Addy is witty, resilient, and impossible not to love, while Ethan is the ultimate protective billionaire single dad with a heart of gold. Their forbidden romance, adorable connection with Ethan’s son, and the surprise twists made this an entertaining and addictive read from beginning to end.
Final verdict: A charming, steamy, and feel-good romance with unforgettable characters, plenty of laughs, and a well-deserved 5 stars!

I absolutely loved how Addy and Ethan meet with Addy being snippy with him and then meeting him in the airplane bathroom and steaming up the room with their sexual antics. Then shortly afterwards her showing up to apply for the nanny position Ethan advertised for his son Oliver. The whole dynamics was hilarious and sweet and them finding it hard to stay away from each other. I enjoyed the element of danger and the mystery of Ethan’s deceased wife’s tragic accident and eventually proving she wasn’t responsible for the plane crash. I laughed so hard at Captain’s antics and chaos he caused. Mostly, I love the whole story and the happily ever after.

What a delectable tale this was! I loved that it was absolutely, wonderfully emotional from beginning to end! The characters are well-rounded and will have you loving them immediately.
The story itself was extremely well thought out and grabbed your interest from the first page, and managed to keep you intrigued until the very last word.
You will absolutely fall in love with Oliver and Captain before you even realize it! The trials and tribulations felt by Addy and Ethan will only strengthen your need to keep reading. Emotions run from complete betrayal to soaring love, and everything inbetween. Be prepared for moments of laughter and downright crying.
Extremely emotional but totally worth the read!.

Summer James’ newest release is a captivating tale of Addy and Ethan’s relationship. The main characters are well-developed, dialogue and banter is wonderful, and the story is fabulous. The chemistry Ethan and Addy share is electric, and Addy’s sense of humor shines through every thought and interaction. As an example, in an interaction with a flight attendant, Addy responds to a flight attendant with: “Yes, I’d love that. I’d actually marry you for this, but I’m currently taking a short break from poor decision-making.” Reading Triplet Babies for my Ex’s Best Friend will be time well spent.

'Triplet Babies for my Ex's Best Friend is a standalone romance in the “Billionaire Ex Appeal” series. This mile-high one-night stand lands with off-limits age gap heat, a dominant single dad, a live-in nanny, and a surprise triplet pregnancy. No cheating or cliffhangers. And a scorching hot happily-ever-after.'

The characters were very appealing and complex and complicated and absolutely perfect together. Plot was intriguing and intense and well paced. World building was excellent and solidly drawn. Thoroughly enjoyed and highly recommend.

Grab a copy, kick back and enjoy!.

Love love love this book
Humor, snark, emotion, growth, steam, and wonderful characters.

(not a spoiler since it is in the title!) The baby on board knowlege doesn't occur until later in the book so we get time to get to know the main characters without that portion of the story.

I really liked this book. There have been other stories by other authors where I get tired of the trope so I get hesitant to pick up but this one was truly wonderful.

No regrets except that I really wish I had grabbed the book before this one!.

“Triplet Babies for My Ex’s Best Friend” by Summer James

-A fun and heartwarming billionaire nanny romance filled with humorous banter, healing, and found family. I received a free copy and am voluntarily sharing my honest thoughts.

Addy and Ethan’s one-night stand in the Mile High Club turns into something much more when she becomes his son’s nanny. Their chemistry is explosive, and Oliver and Captain add plenty of charm. Addy’s sunshine personality helps everyone heal from the past.

A sweet, emotional romance with plenty of laughs, lovable characters and a happy ending.

[Lisa Young · Rating 5 out of 5]

Poor Addy has been through the wringer but is determined to land on her feet in one piece; I admire her tenacity. Ethan is great at doing his billionaire Dad thing, while being unsettled by the past. Now plane obsessed Oliver and the manipulative retriever, Captain, are being healed by Abby’s sunshine. I love Abby’s fun and snarky attitude and how it affects everyone around her, especially Ethan. This is a fabulous, fun, and sweet story of healing and found family!

This is the story of Ethan and Addy. Ethan is her ex's best friend. They have a steamy and hot one-night stand. What was supposed to remain a one-night stand slowly becomes more, especially now that two pink lines are appearing. A steamy story with characters that hold your attention from the first page.
