Oh heck yeah, this is another FANTASTIC story in the Venture Capitalist series and I can’t wait for more!!

Todd is a sexy billionaire that just relocated to the San Francisco area from NYC to open the new office on the West Coast. Being new to the area he doesn’t know many people so when CeCe invites him to a celebration party he jumps on it and hopes to meet some new people. Who he wasn’t expecting to find is a beautiful, smart, successful business woman.

Cynthia has been with SHN since the doors shut down permanently. She has many friends now thanks to her job which are all successful billionaires. While at a celebration party her friend, CeCe, she is introduced to a sexy man. When her life is being threatened, the same man she met at the party, he steps up to protect her and keep her safe.

This is the 5th book in the Venture Capitalist series and it has me glued to the very end. Ainsley St Claire is an amazing author and I am constantly waiting/checking for when she will be giving us more!! This is definitely one of my favorite series and authors!! Can’t wait for the next book 🖤🖤

An intense heartwarming exciting slow build romance. This intriguing storyline is well written and is a standalone in the Venture Capitalist series. It has danger, mystery, suspense, intrigue, and its dramatic, with humor, love, twists and turns that makes this an addicting page turner. The characters are smart, interesting, strong, and have instant chemistry with cameo appearances from previous series characters. I honestly and voluntarily reviewed this ARC.

This was another good read in the series. In this one we have Cynthia and Todd. He has just moved to San Francisco. He ends up meeting Cynthia and falling for her. Her life is crazy right now with her work drama. Thankfully Todd is just who and what she needs to get through it all.

This is a well written book with an intriguing story line. The author brings strong characters in Cynthia and Todd as well as the supporting characters who play a huge role in bringing the story around. The chemistry between the two is hot and steamy and their romance sizzles. She fills the story with drama,suspense,danger and enough twists and turns to keep you on the edge. It's an action packed entertaining book and I loved reading it.

Okay then! Why is this my first Ainsley St Claire book? This was fast paced with interesting characters, hot romance with lots of chemistry and a terrific story. Started at the beginning and read all the way through. Not a dull moment and no “stupid” plot devices. I’ll definitely go back and read the previous books in this series (this one is #5) and anything else that comes from this author. (I voluntarily reviewed an ARC).

What a terrific book! Cynthia and Todd both work in the world of finance and they are introduced by a mutual friend at a fundraiser. They hit it off and as their friendship deepens and becomes something more, Cynthia ‘s role as a whistle blower at her previous company comes into play. The Russian mob doesn’t mess around and they find themselves fighting not only for their lives, but for those around them as well. This was a page turner with twists and turns I didn’t expect. Cynthia and Todd’s amazing group of friends/colleagues had a huge role in making this book such an enjoyable read. Definitely recommend!

I love this book and this series. This book is full of suspense and intrigue. I love to revisit the old characters and like seeing new characters and couples forming. I enjoy the courting, the romance and the chemistry. Todd and Cynthia are very hot and sweet together. I love a true gentleman.

This this series just keeps getting better and better! I love the way Cynthia and Todd meet and how they become friends. Add in all the excitement and how the relationship changes, it was just addicting. It's a longer book (a little over six hours on the Kindle timer) but I still got it all read in about twenty-four hours I couldn't put it down. I can't wait for more

ARC provide to me by Author. I am giving my review voluntarily.

Obsession by Ainsley St. Claire this is the 5th book in the steamy Venture Capitalist series of romantic suspense novels.

I gave this book 5 stars.
Ohhhhh heck YES! this was a hot book. Loved it!!! Ainsley keeps getting better with this series, it's addicting, when you finish one book you wish you had the next to start read.
This series has so many strong, intriguing, smart and beautiful characters that you can't help but fall in love with them, and you feel like you are part of their group of friends, and family.
This book was about Todd Wallington he’s an investment banker for a company called Morgan Wealth Management in New York City, and he came to San Francisco to open a new office for them and manage their West Coast investments. He also came for intentions of dating CeCe, but her heart is already taken by someone else....so she once again was doing her matchmaking with her friends Cynthia Hathaway, she's worked in venture capital for eight years. She worked for BrightStar company which was an investment company, the FBI shut them down due to some treasonous actions by one of their investors and the managing partner. They were told by a whistleblower, and Cynthia was the whistleblower. Now she is in fear for her life because someone is out to shut her up.
Cynthia now works for SHN company doing the same type of work.
Todd and Cynthia have a lot in common, they become friends very quickly- they both really like each other but it takes them some time to cross that line to lovers.
This book has it all, mystery suspense, danger, it's funny, love, hot sex, great friendship's, awesome characters some we already know and new ones. It was wonderful to revisit with them again 😍. In the end Todd and Cynthia found their HEA.
CeCe omg goodness me..... I can't wait for her story already, common pleaseeeee - Mason maybe hummm? 🤔😲.

Having read all of the Venture Capitalist books published so far, I can sincerely say that this whole series has been outstanding.
In Obsession, we meet Cynthia, a new partner in the Venture Capitalist firm SHN and Todd who has recently moved to San Francisco from New York to open a new branch for an investment banking firm. The two were introduced at a function celebrating a congressional candidates victory.
They see each other again when they bump into each other at their condo building. They become friends and meet casually for dinner or drinks, neither of them wanting to take the relationship further since they are living in the same building.
Ms St Clair is very adept at creating fully developed, compelling characters in her stories.
There is so much depth not only in the characters but also the action of the story.
Cynthia had been a whistleblower at her previous company when she uncovered illegal Russian involvement in that firm. What follows is intrigue and suspense that makes this book into a page turner. I loved all the action and the chemistry develop between Cynthia and Todd as well as meeting up with all the other characters from earlier books in the series.
Find out how dangerous the situation with Cynthia’s whistleblowing affects her and those associated with her. Be part of the growing romance between her and hot Todd.
I can’t wait to read the next installment of this series!

4+* ARC – Great addition to the SHN series!!
This ARC was provided by the author in exchange for an honest review. I have read many of the books in this series through ARC programs or various promotions. This series has followed the partners, friends and significant others of the venture capital firm SHN. The books have characters that are very different from many books I have read where the main characters are billionaires.
This is the story of Cynthia and Todd, who we met in prior books. Cynthia has moved to SHN after her prior firm was closed due to their involvement with the Russian mob. As the book opens, Cynthia meets Todd, a NY investment banker who moved to San Francisco to open his company’s West Coast office. As the investigation continues with Cynthia’s old firm, she becomes the target of the Russian mob. At this point since they are friends, Todd insists that she stay with him for her safety.
In my opinion the books in this series get better and better as they go along. This storyline with the Russian mob and how they are involved in business and hacking really added to how the plot unfolded. I also enjoyed how Cynthia and Todd’s relationship evolved from friends to so much more. They were both likable and had great chemistry together.

Verified ARC Reader
Intense, dramatic, heartwarming!
by sewsummore

I really loved this book. It was intense, dramatic, heart warming and made compulsive reading. Cynthia is a woman who fears for her life after becoming a whistle blower to the FBI. Her love interest is Todd an investment banker and new to San Francisco. They begin as friends but soon become much more, eventually falling in love. I loved this book, each page tempting me to read the next. I loved the characters in the book, the friendships between work mates, the honesty of doing what is right in a difficult situation. This book was the complete deal!

This is another gripping book in the Venture Capitalist series, and it’s such a pleasure to get to know Cynthia and Todd. In Cynthia, Ainsley St Claire has written one of the strongest characters I’ve read in a while. From her original courage in turning BrightStar in to her ongoing courage in dealing with the fallout, Cynthia grips the reader’s interest and empathy. Todd too is well-drawn – not too protective, not wimpish, just right. The story has the level of intrigue and tension we’ve come to expect from these books (after all, it includes the Russian mob!), and it is a read-in-one-sitting book.

Great storyline, you really get drawn into the characters right st the start. I loved the excitment of not knowing what was going to happen. Cynthia and Todd wow what away to start a relationship. The steamy sex was making me feel as if I was going through it myself. I could not put the book down it was great. I believe the book was well written. I love reading and feeling what the author feels when they write a book. Well done Ainsley you have written another great story. Love you work.

Cynthia and Todd star in this intelligently written romance with an underlying espionage flavor. Cynthia is a venture capitalist and Todd is an investment banker. Both wealthy, smart, and single. They bond over their eclectic taste in 90’s music and are intellectually matched.
When the FBI made their appearance in her life, this romance turned into a life and death drama with a Russian criminal out to get Cynthia.
Well written with lots of action and fast paced drama.

This was, once again, a truly amazing read from this hugely talented author. Flawlessly written & crafted in such a way that you couldn't put it down even if you really needed to, it was that compelling. Ok I confess it came with me for a toilet break! I was drawn into the story, the danger, the friendships & the sexy as hell hot loving after all the trauma. A happy ever after, it doesn't get better than this. Read the blurb previous reviews, this is a MUST read. Highly recommended.

I received an ARC & this is my honest & volunttary review.

Wow, very intriguing book

This certainly was packed with a lot of intrigue, strong willed people, surprises and of course, love. I really enjoy reading this series because it's so easy to visualize the scenes. The movements of the FBI agents, the security teams along with the main characters. Climbing up the fire escape was something. Hitting a bad guy with a golf club. The group interactions, the trips, meetings and food. It's so much fun visualizing all of it. Going on to the next book...yay! Written by Cindy :)

This is the fifth book in the Venture Capitalist Series and is a great standalone read. Fast-paced and full of suspense. Once you start reading you'll find it hard to put this book down. The characters are well-developed and entertaining. The storyline gets intense when the Russian mob tries to get back at Cynthia for being a whistleblower. Their romance takes on a new turn and is full of danger and drama. I read an arc copy via Booksprout and voluntarily chose to review.

Sizzling Mystery/Romance!
Another great hit for Ainsley St Claire. This is the fifth book in the Venture Capitalist series and a real page turner. Intense drama, intrigue of corporate espionage and the Russian Mafia will keep you on the edge of your seat. Add the charm of San Francisco, steamy romance and wonderfully warm, witty characters and a HEA for a very enjoyable read. Enjoy!

I received an arc copy and am happy to leave my honest review.

This was a great, easy read. I typically lean more towards psychological thrillers so, for me, it wasn’t as intense as I like in the whole Russian mob thing. But, I enjoyed the story and I like the idea of all these love stories intertwined into a group of friends. I can’t wait to read them all!

This book is more suspenseful than the other books. Cynthia is at SHN now that she has secretly whistle-blown her previous company for illegal foreign dealings. She learns that her new neighbor is the cute guy who followed her friend to San Fran. However, things just keep getting from bad to worse. Can her new romance with Todd survive? 4.5 stars
