Charlie Thorne and the Lost City by Stuart Gibbs

4.0

I read [b:Charlie Thorne and the Last Equation|43259902|Charlie Thorne and the Last Equation (Charlie Thorne #1)|Stuart Gibbs|https://i.gr-assets.com/images/S/compressed.photo.goodreads.com/books/1566731884l/43259902._SY75_.jpg|67082555] and thought it was fantastic, so when I saw a second book, I knew I had to read it as well. These books are action-packed adventures with lots of history and science woven into them as well. In this second book of the series, Charlie is attempting to hide out in the Galapagos Islands when she is asked to help decipher a coded message apparently carved into the lower shell of a Galapagos tortoise by Charles Darwin. Thus begins the dangerous race across South America and into the heart of the Amazon rainforest to find the treasure Darwin discovered and then never talked about once back in Europe. Charlie is incredibly smart, and the dynamic between her, her half-brother Dante, and his CIA partner Milana is great.

I appreciated that Stuart Gibbs included an author's note at the end of this book to clarify the aspects of the story that were true about Darwin and those that were pure fiction. These books do include some violence, so I would classify them towards the upper end of middle grade. I will absolutely be adding this series to my middle school class library.
