Last book of this novella series, realistically they could have all been combined into one book. Hannah' and Ian's story is another dual timeline, taking place at CalTech/NASA and Norway. Ian is actually Mara's cousin (Mara is from book 1), which I thought was a cute tie in. In this book we see all of the girls reunited in Houston, the first and only time they're all together in the present day timeline. I think this series could have used more of that. After reading this book, I feel like the first book is definitely the best. While the MC is pretty well developed, her love interest really isn't. Given more pages, he could have been better developed and may have been a great full length book. I actually enjoyed the plot. The ending was ok but I'd have liked the end to see all of the girls together. All in all, not a TERRIBLE Novella series but I'd rather have just had full length books of book 1 and 3.
