Once Upon a Contract: The Siren Prisoner

Rate this book
Male agents are nothing new at Fairy Godmother Inc., but Jensen King is something else entirely.

Once a hardened operative with a dangerous mafia past, King is thrust into the glittering, deadly world of the high seas — captaining a legendary ship through treacherous waters and enemy territory. For the first time in FGI history, the rules are being broken, and the stakes have never been higher.

But the greatest challenge isn’t the mission… or the enemies closing in.

It’s the fierce, untamed siren who crashes into his life like a storm — a woman whose fire matches his own, who challenges every rule he’s ever lived by, and who awakens dark desires he swore he buried long ago.

Now King faces an impossible complete the mission and protect Fairy Godmother Inc., or risk everything — including his heart — for the one woman who could either redeem him… or destroy them all.





THE SERIES

A magical letter from a fairy godmother. The promise that all your romantic dreams will come true if you sign on the dotted line. What would YOU do? Would you travel to a magical world to win the heart of a gorgeous prince? What could possibly go wrong! Right…?

Five women get to embark on an adventure of a lifetime, full of danger, excitement, and most of all, true love. You might wonder why these girls chose to compete against each other for a man aka target?

I read this last year. It’s the last book SO far in the series. This one is different because you get the guy as an agent and it was awesome and funny and spicy and just everything. The ending is a bomb shell and I think we are all dying to know what happens in book 8! OH and they bring back an agent from a past book who is SO my favourite because she is FUNNY as hell!

Amazing!

I was in a major reading rut until I discovered this series. Since then, I have read all 7 books in 11 days (it's hard to read when you have to work) and can NOT wait for the final book of the series!

This book was absolutely amazing, and I just couldn't put it down. I loved how instead of women trying to change the heart of a man, it was men going after a woman. It was a great change. This book also set up the last book of the series perfectly, so I'm excited about that.

This book didn't have the magic that I felt in the others. I understand that the plots with Pierce was very important to set up for the next book but I thought because we skipped a lot of things that usually we get. Usually, we get them falling in love before the main target touches the necklace and up to this point we never really went back to the sea witch plot point. Then it kind of got kind of confusing from him being the dragon king and realizing that she's his mate and all of a sudden he realized that he loves her. The author tried to build this change from interested and jealous to love but it didn't translate for me. It also seems like he had a slight personality change but I don't know if that's just cuz his dragon awakened.

Now, this is what I'm talking about. This one is full on from the start right to the very end, and OMG what and ending it is. Talk about heart-pounding action adventure and spice. Another one from FR Black that does not disappoint.

Maybe because I just want to get to the last book? Maybe Im a but annoyed there were a lot of grammatical errors and formatting errors for a ebook i purchased, maybe I need a break from the series? But this one was my least favourite? But it wasn’t because I didn’t love the story, it was because I felt like the writing was rushed, and I found myself skimming through the book a lot…. Maybe I’m in a slump?

Blah! 😑 BUT I STILL LOVE THE SERIES AS A WHOLE and it’s a MUST READ to get to the last book!!!! And I’m sure its because I’m just in a funky mood

This one was fun if a little short. I realize that this book was really just a means to get to the book on Pierce and to set the stage for his own “mission.” And the eventual take down and redemption of FGI. However, I love the story from the male perspective - Jensen and Delilah are of course super steamy. What’s not to love about a mermaid dragon shifter romance? I mean seriously.

AMAZING

I can not wait for book 8! Ahhhhhh! This was the most stressful book at the end and I loved it haha! Jensen and Dolly were hilarious. The dildo scene had me laughing to the point of tears! Bravo author!

I've only rated this 4 starts since it's a major cliff hanger for me.
I'm not so happy with the ending though as always she writes beautifully. I can't wait for the book 8.
All of her characters will make you fall in love for them. I have a lot of book boyfriends from FGI series ...

Mermaid, Black Beard meet UIA

Wow! The treasure hunt of a lifetime, to save the universe from evil. Dollies back with many more TP shifters to save the day. Can they save Prince Charming, let us hope they can for FGI sake.

I loved the idea of the book and I feel like it had so much potential, but there were too many bits that just seemed so rushed, and that some storylines that were just skipped over. The ending was too rushed for me, I kept checking to make sure I didn’t miss anything.

Different from the others in the series because the main character was a male this time going after a female. Really liked it! Half of the story was the same plot as the others and the other half had more outside action happening to lead into the last book! Very excited to see what happens next.

I can’t even form words. The cliffhanger! Ahhhh! Thank goodness book 8 is finally out

Romantasy, secret agents, little mermaid with dragons, love/hate, final turning point for the series, major political power plays, f*ck the system attitude

⭐️⭐️⭐️⭐️⭐️

This story would probably have you thinking back on Pirates of the Carribbean quite a bit. Very chaotic but was interesting to have a male character leading the charge. Dolly is possibly a Charlie's Angel reincarnate.

This is a steamy little mermaid retelling where Ariel’s character is a siren assassin named Delilah and Prince Eric’s character is a badass Captain/ Pirate named Jensen aka King. The book reads as awesome as it sounds!

Great audio performance on Galatea. I really liked the characters and how they finally realized they loved each other. Great HEA, but cliff hanger for FGI !!! Oh no! Pierce!

This one was Top 3 of the entire series for me. Jensen is a BAD ASS and so is Delilah. Perfect match. and it was soo awesome to see the roles be flipped this time around.

Another of my all-time favorites by F.R. Black in the FGI series!
I love that it features a different type of main character (no spoilers here). The agent—OMG—I laughed out loud so many times and face-palmed 😂. An absolute perfect match for the main character.
This series is action-packed and loaded with wit, spice, and intrigue. It literally has it all. I could not put it down.
Follow the series all the way through, then continue on to the Dom/Pierce Academy series. Well worth your time—you won’t be sorry!
