Overview:

65-73 Mustang Long Tube 260-351 Raw 409

JBA long tube headers are the number one choice for maximum performance gains and high RPM efficiency. Available in 409 or 304 Series Stainless Steel.

    UGH SO GOOD!!!
    Format: Paperback
    Such a good book! The way the story is written and how the characters are portrayed leaves you wanting more! A tad bit of a slow burn but so so good and worth the wait! Personally I bought both the book and audio book because I couldn't put it down! This book had me (A man) kicking my feet like a little girl and holding back tears throughout the story. I just love love and this story is just so beautifully written!

    Slow burn with a sprinkle of fantasy.
    Format: Kindle
    It was alright. Written well. Story was decent. But it just lacked something. It's the slowest burn I've ever read, which is fine. I felt like the knight (main character) was kind of weak and whiney… And I expected the strength of a knight! The first chapter is filled with a lot of background information, but then it's like the story doesn't really reference it again. I would have liked a bit more information that first chapter before just heading right into the story in chapter 2. Things could have been explained more in general. There could have been a lot more detail and explanation abiut the fantasy side of the book. It was just like a straight romance with a sprinkle of fantasy. Overall, it was decent, but I probably wouldn't recommend it to someone unless they asked specifically for a slow burn with a little bit of fantasy. I received an advance review copy for free, and I am leaving this review voluntarily.

    A Forbidden Romance With Teeth
    Format: Paperback
    First off: I loved the couple. Della, our acting princess, and her sharp wit and determination to survive were a refreshing change from the damsel type princess. Galeon was a woman of honour and yet so head over heels with the fake princess that she can't keep away. Birch does a great job of building a magical world and drawing you into it so that you kept turning pages until the end. And that page-turning was also spurred by the slow burn will-they-won't-they romance between the heroines who had much to lose if they crossed the line. I've purchased all three novels and will review Her Blushing Hero just as soon as I've finished.

    AMAZINGGGGG
    Format: Kindle
    My first sapphic read and i think I’ll forever be attached to her writing! Already finished the consecutive two books in the series and I’m back to rereading them all! Such a great author to draw up such vivid pictures through words, especially the spicy parts! Great slow burn, so much action and lesbians are normalized in this world??? I loveeee it! Thank you Ms. Mariah for giving your readers a beautiful place to escape! Can hardly wait for spring when she releases the 4th book 😍
