Why I love it

Megan Goldin
Author, The Night Swim

On the day my novel The Night Swim was released back in August, the city where I live in Australia was put under the toughest lockdown in the world. So it was a wonderful escape to immerse myself in the pages of The Girl in the Mirror and travel vicariously through its characters—from the beaches of tropical northern Australia, to the translucent Andaman Sea in Thailand (one of my favorite travel destinations), all the way to the Seychelles.

But if luxurious travel alone isn't enough to make you snag this book, then let's talk about the plot. Identical twin sisters Iris and Summer are mirror images of each other, but while Iris has no marriage prospects, Summer has a gorgeous (not to mention wealthy) husband. When Summer disappears in a freak yachting accident, Iris poses as her sister by pretending that she (Iris) was the twin who had gone overboard. Why? Because their millionaire father has offered his $100 million inheritance to the first married daughter to produce an heir. And now, living as Summer, Iris is one step closer.

Throw into the mix a too-good-to-be-true husband with unexpected sexual fetishes and a missing person case on the high seas, and you have all the ingredients of a twisted and compulsively readable domestic suspense story. When reality gets you down, a jet-setting thriller is the ultimate escape, and that’s why I loved this novel.

Twin sisters Iris and Summer are startlingly alike, but beyond what the eye can see lies a darkness that sets them apart. Cynical and insecure, Iris has long been envious of Summer’s seemingly never-ending good fortune, including her perfect husband Adam.

Called to Thailand to help her sister sail the family yacht to the Seychelles, Iris nurtures her own secret hopes for what might happen on the journey. But when she unexpectedly finds herself alone in the middle of the Indian Ocean, everything changes. When she makes it to land, Iris allows herself to be swept up by Adam, who assumes that she is Summer.

Iris recklessly goes along with his mistake. Not only does she finally have the golden life she’s always envied, with her sister gone, she’s one step closer to the hundred-million-dollar inheritance left by her manipulative father. All Iris has to do is be the first of his seven children to produce an heir.

Iris’s “new” life lurches between glamorous dream and paranoid nightmare. On the edge of being exposed, how far will she go to ensure no one discovers the truth?

And just what did happen to Summer on the yacht? Only Iris knows...

    ⭐️⭐️⭐️⭐️⭐️Short, sweet, and SNARKY- my favorite! I loved the twists and turns; it was thought provoking, but not scary. I devoured this book! I am looking forward to more books from Rose Carlyle!

  • Cedar Grove, WI

    Thoroughly distraught by this book. Just finished it and in complete shock. As soon as i thought i had the twist, it threw me. The ending was a total shock. ⭐️⭐️⭐️⭐️⭐️ for totally stumping me.

  • Clermont, FL

    One of the best I’ve read in awhile! You’re “in” on the life secret Iris is trying to keep, reeling about how she can make it can last forever. As I read the LAST SENTENCE I was like “what?!” So good!

  • Pewaukee, WI

    Books about sibling rivalry are always great but when the book is a thriller, it’s even better. If you’re like me and like to really “getting into character’s heads” while reading, you’ll love it.

  • Willoughby Hills , OH

    OMG. Didn’t not see that coming. Any of it. Was trying to figure out how Adam didn’t know his wife wasn’t his wife. Story seemed slow at times, Seychelles scenes didn’t seem important. Loved it tho

  • Trafalgar , IN

    ⭐️⭐️⭐️⭐️. Really enjoyed this. Very good twist. The only thing keeping this from being a 5 star is all the ship terminology and description of it’s workings. I really just didn’t care.

  • Wichita, KS

    This book threw me for a loop, multiple times. I just finished it and am still reeling. Omg. It was a very quick read, but HOLY MOLY! It reminded me of “A Simple Favor” w/ Blake Lively & Anna Kendrick

  • Saint Paul, MN

    Wow! This book kept me engaged the whole time. I thought I had the twist figured out, but the ending left me shocked! My feelings about the characters changed, too, which kept me on my toes. Five ⭐️s!

  • Albuquerque, NM

    Ugh this book was good in the “I can’t put it down” sense but the ending made me feel sick! Loved it! It was not what I was expecting, but in a super interesting way! Definitely a suspenseful read!

  • Buffalo, NY

    Gosh, the twists and turns in this book are unbelievable. And the end, I was like SHOCKED. I thought I had it figured out, but I was wrong - which is the reason this book is getting a ❤️! Mindblowing!

  • Minneapolis, MN

    Mirror image twin sisters with a $100 million inheritance on an ocean going sailing voyage. Only one can inherit the money. How strong is the sisterly bond, and how well do they know each other as adults

  • Edmond, OK

    I’m all about the thriller genre, so it takes something unique to keep me on my toes- and wow, did this one succeed! I’d been hunting for a can’t-put-it-down read, and I absolutely found one here!

  • Charlotte, NC

    Slow build, cool twist at the end. Edit: 2 years later and I still randomly think about this book and it’s twist ending. Darn good in hindsight. I think I was just mad it didn’t end how I wanted lol

  • Murrieta, CA

    I don’t read a lot of thrillers bc I can usually guess what’s going to happen but this one completely threw me for a loop. I loved the morally gray characters and crazy family dynamic. A great debut!

  • Hartwell, GA

    Wow what a wild ride!! This book is full of shocking moments, more twists and turns then you can count, and the ending was ????. In my opinion, this is exactly how a thriller should be. This one did not

  • Mundelein , IL

    I’m a sucker for twin stories -narrator Iris is the mirror twin of Summer Rose from Wakefield, AUS (they technically are Wakefield twins, too!). Fast-paced & thrilling plot makes this hard to put down

  • Novato, CA

    The sailing terms used were a little off-putting for non-sailors. But once the story kicks in and the sisters go sailing, the book picks up and never stops. And there is an ending you won’t see coming

  • Coraopolis, PA

    What. A. Ride. I absolutely loved this book. I went in and out of hating Iris, but poor dead Summer wasn’t so sad after all. This was not the twist I was expecting but it was incredible. I need more!

  • Plainfield, IL

    This was such an interesting read! I couldn’t put it down. It tugged at my heart strings. It was a spiral of emotions. The time and place setting really added to the storyline. I absolutely loved it!

  • Indianapolis , IN

    There is major detail about sailing in the beginning of the book which was a bit tedious but, oh my God, get through that and you’ve got a book that can’t be put down with an ending you wont forget!
