Nice to be back in their world

I have enjoyed the entire series prior to this one and have missed these characters!

I forgot how addictive their world (and adventures) are!
The action and battles they faced were full of energy and danger, and I loved watching them take care of the bad players.

Bryn Harris is an easy character to enjoy. Her chemistry with Rush flows well, and they were good together. I was a bit frustrated with a couple things that I wanted to move differently, but overall it's a steamy, addictive, engaging read that I recommend.

Please read the series in order for the best experience with this read.
I can't wait for the storyline to continue and to see how Killian and Story work together. IYKYK! :)

I've loved this series and the characters from the very beginning. This story did not disappoint. It's one wild ride with some spice and thrill thrown in. Do yourself a favor and give it a go! And while you're at it, read this Amazing series.

When you mentioned a crossover there were several possibilities and I thought I had it figured out at the beginning but I was wrong 🤔 But when I was positive I knew who it was I knew it would be an exciting mix for this story.

The first chapter sucks you right in! Bryn is just as bad@ss as her mama. To this day I still think about that scene from Layla’s book. IYKYK 😉 Bryn and Rush’s chemistry was there from the moment they met.

I need the next book in this series Stat please

Thanks Jasinda and Jack for an ARC ♥️

I voluntarily read and reviewed an ARC of this book. This is the 12th book in the Alpha Book series. It can be read as a standalone.
Being the daughter of Nicholas & Layla Harris comes with 24 hour guards. Bryn just wanting some time to herself to unwind, looses them. Only, this time she finds herself being kidnapped and finally able to use some of the skills she has been taught.
Rush needs money and fast, and Pugli knows the exact amount and the reasonings to why. Which is why Rush will do any job Pugli ask. Even if it questions his morals.
I love that we got to revisit some of our other fan favorites. Keep them coming!

Buckle up for a wild ride and some crossovers. Bryn and Rush are so great together. Rush’s little girl steals the show once she comes into the picture. I love that characters from other series are featured. I can’t wait to see what the next book has in store for us, buckle up it’s a bumpy ride.

Alpha, bad assery and sexy action packed read. This addition with Bryn and Rush story is so fun to journey through. I would love to see this series adapted into a tv series.

Wow!! I just love this series. The AIS need to save one their own. Fast paced and guns blazing and love. A few surprises and along the way. With a cliff hanger I am looking forward to more.

Jasinda knocked it out of the park again.

I didn't expect the men from Club Sin to make an appearance in Delta.

I don't think in the beginning Bryn realized how strong she truly was. Meeting Rush was good for her. Even if their relationship took a few detours. Rush was carrying some major baggage. As a prior SAS soldier, he'd seen more than he wanted to. But he was loyal to a fault. After leaving, he had to do whatever he could. He needed a lot of money. He had to have it. There is no wavering from his goal. Nothing could stop him. Not even a 6 foot, gorgeous, brassy spitfire like Bryn Harris. He couldn't fall for her. He had a mission that was more important than anything. As for his conscience, well that could go to hell. He knew someday he'd meet up with it again. But as for now, he couldn't let that or his heart take him from this path. Bryn Harris was just an end to a job. He wasn't going to let her be anything else.
Bryn was cautious when Rush saved her. But she still felt he was hiding something. After awhile she became more comfortable. But there was still a little nagging presence in the back of her mind. "Why is he doing all this for me? What's in it for Rush? Could he really be a true hero running into danger for me? What's in it for him?" As Bryn starts to relax a little around Rush, the worst that could happen, does. Was she wrong about him? Probably. Maybe.

Good Story, Horrible Typos

This was a good story and a looong time coming. I was excited to get back into the lives of this crew and see what the kiddos are up to. I enjoyed reading about Brynn and Rush and their escapades and I’m excited to read the next adventures with Killy and Story.

With that being said, here’s where the 3 stars come in…. The spelling typos and errors in this book were so numerous, it was hard to understand at times. I was reading this book on my Kindle app on my iPad/iPhone, so maybe it was just the conversion from print to e-reader, at least that’s what I’m hoping happened. I would hate for an actual print book to be this bad, I would want my money back if I bought the actual print book and it had that many errors. At times I thought maybe it wasn’t edited and the original rough draft was just put out into the world, that’s how bad it was. I love Jasinda’s stories and have never had an issue like this before, so I will continue to read her books and hope for the best for the next one.

Finally, we’re back on track!

I got into this series but as you go they get umm … not very good. At least to me and that was with the start of the adult kids.

This book however though it started off where I thought here we go again; crested and it’s a good read. It didn’t even finish and the epilogues (there’s 2) are the start to new old characters and new new characters stories. So I guess I’ll continue on until the end!

Bryn at first after the whole freezing and talking way too damn much; I couldn’t stand her. Then she grew on me. Rush while of course we knew he was the “bad guy” he wasn’t ever really the bad guy; loved him at first read. Melt my heart with his scene in the hospital with his daughter!

All in all I’m happy I continued on this journey.

Delta is book 12 in the Alpha series by Jasinda Wilder. This can be a standalone but I think it really helps to read the series in order to get the best experience from this series. This book is Bryn and Rush’s story and it is a sexy action-packed roller-coaster journey with lots of surprises that keep you hooked. I can’t wait for the next book. I loved this book and highly recommend it!

[Lori · Rating 3 out of 5]

Book was very hard to read all the way through with all the spelling errors and grammatical errors. I’d be shocked is someone proofread this book. I also didn’t know it was in kindle unlimited so I preordered it and paid for it. Very frustrating.

[Shirin Rasheed · Rating 5 out of 5]

Delta by Jasinda Wilder is another great page turning story in Alpha Series. It is so amazing and wonderful to read. A Must read for all fans of this series.

Highly Recommend.
