The 12 Days Ultimatum

Rate this book
“I don’t take kindly to ultimatums.”

Nobody gives FBI Supervisory Special Agent Lucas Alexander ultimatums. His reputation as a hard-ass perfectionist is well-deserved. There’s a reason he’s the go-to person for agents, the community of Silver Pine, Idaho, and even the Salt Lake City Field Office. For Lucas, the job always comes first. Always has.

Always will?

Because Lucas does have one weak spot, and his name is Special Agent Riley Christopher. Two days ago, Riley delivered his boss an ultimatum: prioritize their relationship or end it. Now Lucas has a choice. The job or the relationship? Lucas has to decide whether he’s capable of balancing love and duty before the twelve days of Christmas are up.

This was full on romance. No mystery. No other distraction. All romance. And it was awesome!

So pretty please, Josh Lanyon, can you incorporate this into your usual books? This is my one complaint about your books. See? You CAN do it.

Molto carino. Però sembra come se mancasse un capitolo tra gli ultimi due. Non si può non mostrare come siamo arrivati dagli eventi del penultimo capitolo a quelli dell’ultimo! Non si può saltare il chiarimento finale! Era quello che avrei voluto leggere nel corso dell’intero romanzo :(

Lanyon usually excels at second-chance romance.

Turns out, she's also excellent at the "fighting to keep your current relationship" kind of romance. Because wow, this novella really packs a punch. I spent a good portion of it wanting to lovingly slap Lucas upside the head for being an absolute idiot. I mean… HOW can you be this slow, SSA Lucas Alexander?!?

That said, it's still genuinely romantic - and surprisingly hilarious at times. Case in point: drunk Lucas writing a field status report about his relationship with Riley. Sir. Please. Absolute idiot.

And yet… still swoony. 💙

PS: Note some typos? Don't usually notice it in Lanyon's self-published but somehow I did here ​🤷​

This just popped up out of nowhere, but I couldn't help taking a few minutes and giving it a quick read. Even though it was short in length, it got the job done. *I can't believe I just wrote that* 🤦‍♀️🤣

The truth is, when everyday life is going smoothly, it can be easy to forget how important it is to remind our loved ones how much they add to our lives and that we see them. Being on the receiving end is nice also!!! 🥰

Short but Beautiful❤️

There are few things more exciting, when it comes to books, than the unexpected release of a new Josh Lanyon book. This might have been a novella but the author wrote a beautiful love story in her usual poetic nostalgic style almost making you think you are reading a book from the 50s but it’s actually set in the present.

Lucas and Riley were FBI agents based in a small satellite office in Idaho. From the moment Lucas interviewed Riley he was drawn to him and three years into their relationship Lucas was content. He loved Riley but had no idea how to show him, Lucas lived for his work and working alongside Riley was all he needed.

Riley on the other hand loved Lucas but he needed more. Every weekend they were the on-call officers and every year the rest of the staff took off for the Christmas vacation leaving Lucas and Riley on-call and Riley was sick of it, he wanted more. When he gives Lucas a twelve days to Christmas ultimatum Lucas is at a loss to understand the problem, until Christmas creeps closer and he thinks he has lost Riley for good.

It might have taken Lucas a while to understand the assignment but it was beautiful watching him unravel, grovel and pull out all the stops to show Riley just how much he loved him.

I will always recommend a Josh Lanyon book.

Another lovely holiday goodie from J. Lanyon. As with some of her other shorties, this one starts as if you should already know the characters. But that was fine; I just jumped in. Two FBI guys who work together and are in a relationship, Riley and Lucas are having relationship issues. Riley has issued an ultimatum of sorts and Lucas is flummoxed at what to do about it. Nice sense of a backstory here with crucial tidbits about who each man is as a person. Fulsome story in 77 short pages. No heat, but that's fine. Really enjoyed it.

Lucas is Riley's boss and the both work for the FBI.
12 days before christmas Riley delivers an ultimatum to Lucas.
I did feel alot like just knocking these 2 men's heads together. A little communication was all that was needed.

By the by for a short book I thought it was quite expensive.

Of course, I enjoyed it. It's a JL book - and "relationship in trouble" is her bag.

...but I also don't feel like Lucas did anything to prove to Riley that he wouldn't revert to the status quo as soon as Riley is comfortable again.
