Cover and plot reveal for Charlie Thorne and the Lost City

Hi all.  I am thrilled to be able to share the cover and plot for the second book in the Charlie Thorne series, which will be published on March 2, 2021.  Here’s yet another masterpiece by the great Lucy Cummins:

As you can see, there’s all sorts of great action and adventure here on the cover alone.  Here’s the official plot synopsis:

Charlie Thorne is a genius.
Charlie Thorne is a fugitive.
Charlie Thorne isn’t even thirteen.

After saving the world, Charlie is ready to take it easy in the Galapagos Islands. That is, until she’s approached by the mysterious Esmeralda Castle, who has a code she knows only Charlie can decipher.

In 1835, Charles Darwin diverted his ship’s journey so he could spend ten months in South America on a secret solo expedition. When he returned, he carried a treasure that inspired both awe and terror in his crew. Afterward, it vanished, never to be seen again…

But Darwin left a trail of clues behind for those brave and clever enough to search for it.

Enter Charlie Thorne.

In a daring adventure that takes her across South America, Charlie must crack Darwin’s 200-year-old clues to track down his mysterious discovery—and stay ahead of the formidable lineup of enemies who are hot on her tail.

When an ancient hidden treasure is at stake, people will do anything to find it first. Charlie may be a genius, but is she smart enough to know who she can trust?


As usual, I am not going to answer any more questions about the plot, because the more you know, the less fun the book will be to read.

But I will say this.  I test every one of my books out on my kids and they LOVED this one.  Once we hit the last half of the book, they wouldn’t stop reading.  So hopefully, all of you will love it too.  I’m really proud of it.

Although it doesn’t come out until next March, it is already available for preorder here.

  1. My Questions:

    1. Is Charlie not helping the CIA anymore? Or is she just hanging out for a while?

    2. Does Dante and Milana know where she is?

    I understand if it’s classified.

  2. This is probably a stupid question:

    Since it probably involves El Dorado, do you know Geometry Dash and the levels “El Dorado” by AncientAnubis and “The Golden” by Bobobobobo?

    You don’t need to answer it if it’s unnecessary, it was just a thought I had.

  3. How long does it usually take for you to write a book? I want to write one, but I want to know how long I’ll be most likely writing it. Thanks.

  4. Curious –

    Everyone writes at different speeds. I work on a book for about two years before it is published.

  5. Two questions. 1. Are you finished writing Charlie Thorne 2? 2. Are you currently writing Charlie Thorne 3? Thanks.

  6. Pro –

    Since CT2 comes out in less than three months, I had better be done writing it. Right now, it is being preapred for printing.

    I am working on CT3.

  7. What other books are you working on other than CT 3?
    By the way, I love your books!!!

  8. I really love how smart CT is. She reminds me of a series I read called Keeper of the Lost Cities. But CT is definitely my favorite.

  9. im so super excited to read CT2.(and 3) will Charlies CIA cousin be an important charcater later on? i really liked him.

  10. Pandorabusche –

    Do you mean Dante? He is not Charlie’s cousin. (I don’t want to spoil who he is, but you might want to check the book again.) And yes, he will be important in the series.

  11. Mr.Gibbs…
    What is your favorite book or a book that really inspired your writing? This is Ice Queen using Smokescreen’s name for reasons I explained to you earlier.

  12. Ice Queen/Smokescreen –

    The Westing Game, the Ecyclopedia Brown series and the books of Michael Crichton really influenced my books.

  13. love ur books –

    At this point, what happens in future books is classified. Please see my blog post about Questions I Can’t Answer.

  14. Mr. Gibbs,
    How do you come up with this stuff? The way CT figures things out is so complicated. Did you figure out her whole thought process??

  15. Mr. Gibbs-
    1) How do you do this? The way CT connects the dots is crazy cool. Her brilliance is pretty much your brilliance (Cuz you created her?)

    2) How do you know so much about all the places your characters have been? Its like you have lived in all of them. Thanks!

  16. Balloon –

    As the author, I HAVE to figure out Charlie’s entire thought process. How else could I write what she is thinking?

  17. Balloon?

    I do my best to visit the places Charlie has gone (o to write about places that I have visited) although sometimes, I just have to do research. And spend a LOT of time looking at Google Earth.

  18. Is it fun to travel to so many places for your writing? Who pays for that? the publishers, or you??
