Into the Deep

Delta Shield Security

Assigned to protect his best friend’s sister, a battle-hardened operative must break every rule in the book to keep her—and his heart—safe in this pulse-racing romantic suspense novel by Wall Street Journal bestselling author Brittney Sahin.

Audrey Langston is done with love. After heartbreak, betrayal, and secrets that shattered her life, all she wants is peace—and to raise her son in safety. But when a violent home invasion rips that fragile calm apart, she’s thrust into a web of shadowy enemies, where someone is watching her. Hunting her. And the threat may be tied to a past she thought she’d escaped.

Alejandro Rodriguez doesn’t trust easily, not after the woman he once loved nearly killed him. Which is why protecting Audrey should be just another mission—the problem is, it’s personal. She’s not only his team leader’s newly discovered sister, but she’s also the woman he’s spent the last two months trying to resist.

As danger closes in and buried lies come to light, the lines they’ve drawn begin to blur. Passion ignites, trust is tested, and every step takes them deeper into a deadly game.

In a world where nothing is as it seems, their intense connection may be the only truth left…if it doesn’t destroy them first.

Good way to pass the time!

Good story!
Complex though. Messed up and started in book 2 so be sure you start the series in the right order!

Chefs Kiss

Into The Deep is Brittney Sahins second book of Delta Shield Security and honestly, I didn't think it could get this good! The audio is absolutely fantastic! The narrators are great and I highly recommend this!

great story flat narration

Great story, but the male narrator was flat and was horrible at accents. It threw me off so much I switched to text. The female narrator was great, though.

Love the story

I love all her books. Just would like the title of the books in the previews

Simply fantastic!

Into The Deep by Brittney Sahin is a book that delivered so much more than my very high expectations for it. The book is the second of three in her Delta Security series and not only continued the high standards of the first book, Against All Odds, but took those standards even higher.

She weaves together characters in a story that instantly leave you feeling invested in their circumstances, relationships, and evolving suspense. She creates scenes and descriptions that make you feel as though you are present for the action. The descriptions are never too much but create a perfect setting. As I listened, I found my heart raced, I swooned, and I felt every emotion from anger and frustration to pure joy and laughter. This book brought all the fun and action delightfully from start to finish. The trope and developing characters are perfect. The only thing better was the author throwing in a few familiar names and characters from another series or two she wrote. It’s like visiting or checking in on old friends. My smiles became broader. Whether there was a mention or two of familiar characters, or full character engagement, it was delightful. Although nothing is lost if you are unfamiliar with those characters.

The story was constantly filled with suspense. When I thought I finally had the mysteries solved, the story took another twist. Every twist was artfully created with perfect timing. The story was a constant source of fun and never felt too easy or too complicated. The author’s writing style is engaging and I couldn’t quit. Simply, I loved it in every way.

It is helpful and recommended to have listened to Against All Odds before listening to Into The Deep. It will make it even more enjoyable as some characters and stories are evolving from the first book in the series. While you’re at it, I recommend grabbing all of Brittney Sahin’s books. You’ll wish her characters weren’t fictional.
