That ending 😫
Format: Kindle
I fell into a false sense of security and really thought this was gearing towards a happy ending. Then I realized there’s no work they don’t punish Andrew. I really liked Vale’s character. I don’t normally read books with pregnancy but going into this knowing she was pregnant made it more enjoyable for me. I loved Bishops devotion to her and her happiness. I also loved that Holt and Mercy couldn’t fight their attraction to her. I love scent matches so very much. I’m so curious to see how this duet will end up. And I need to pay more attention and notice that a book I’m starting is a duet to begin with lol

oh wow
Format: Kindle
I just knew there was something about Cooper! I’m wondering if he’s about to be included but damn I’m glad he’s at least not a rapist and creepy guy, he just got called on assignment and had to go! This should be interesting! She’s gonna run and then what’s his face is gonna grab her. I’m worried! Wow that was a great book and cliffhanger! Loving this!

Fantastic writing and non-stop action
Format: Kindle
This is a promising, fantastic beginning to what will be a 4-book series. Some readers may be content to read only the first 2 books, but I think you'll find that the story is so good that you'll want to keep reading books 3 and 4. Book 1 is about omega Elvana's introduction to the "Starling" brothers and their search for another missing person, Kelly. It's a bit of a rocky start, with deception and betrayal a key element. Hardly an auspicious beginning. Each member has their own path and purpose in the pack. Their interactions and the resulting narrative are so well-written that I found it difficult to put down. There is a cliffhanger that will have you reaching for book 2 as you finish, so make sure you have it on hand.

Fun read
Format: Kindle
I'm not really into mafia books but I love Roxy Collin's other series so I decided to give it a try. It had the same great romance, spice, swoon-worthy characters and exciting plot that are her signature. Arben was my favorite, although it was a bit sudden how quickly he changed from ignoring her to wanting to be pack. There were almost too many twists/layers of lies to keep track of but I'm looking forward to reading the other books. The only thing that detracted from the story for me was the need for a bit more proofreading. It was mentioned that Kelly is a female and male at different points, leading me to think she changed her mind at some point about the character's gender but didn't go back and edit it to align in all places. Like another reviewer pointed out, step siblings are different than half siblings. They are incorrectly referred to as step siblings because they (allegedly) share the same biological dad. There are a few other typos as well but those aren't a big deal.

Stepbrothers, Secrets, and Sizzling Heat
Format: Kindle
Twisted Lies by Roxy Collins is a wild ride through family secrets, amnesia, and a steamy stepbrother romance. When Kelly discovers her life is built on lies, she ends up tangled with three alpha stepbrothers and an assassin who once helped her through a heat. The tension? Off the charts! The heat is real, and the complications are messy in the best way. Full of twists, secrets, and fated mates? You'll be hooked from page one! Love omegaverse drama with a dash of taboo? This one's for you!
