We are so excited to share our May Adult hint, Secret Laboratory! ⚗️ 🕦⁠

From the bestselling author of The 7 ½ Deaths of Evelyn Hardcastle comes a story about a ticking clock, a deadly fog, and an unsolved murder that's the key to saving what's left of the world. This first print run will also include beautiful sprayed edges!⁠
Outside the island there is the world destroyed by a fog that swept the planet, killing anyone it touched. On the island: it is idyllic. One hundred and twenty-two villagers and three scientists, living in peaceful harmony. The villagers are content to fish, farm and feast, to obey their nightly curfew, to do what they're told by the scientists.⁠

Until, to the horror of the islanders, one of their beloved scientists is found brutally stabbed to death. And then they learn that the murder has triggered a lowering of the security system around the island, the only thing that was keeping the fog at bay. If the murder isn't solved within 92 hours, the fog will smother the island—and everyone on it.⁠

But the security system has also wiped everyone's memories of exactly what happened the night before, which means that someone on the island is a murderer—and they don't even know it.⁠

On sale now through May 14th (or until we sell out) the clock is ticking to snag this highly anticipated box! Boxes are expected to ship at the end of May.⁠

    I loved the book but kind of disappointed in the gifts for the price point


    So fun! Can’t wait to dive into the book and the gifts!


    It’s really awesome and worth it!


    The book was great

    Love it!

    I used to only purchase certain boxes, but I took the plunge to always get the Adult box, and I'm so glad I did. Even if I don't love the book (I usually do!), the experience is so fun and inspires me to read.

    I love Once Upon a Book Club. Each month offers a book with a collection of gifts that bring the words on the pages to life. My collection is growing and I even had to purchased new book shelves. I love the boxes!

    Once Upon a Book Club is a reader’s delight. The concept of this book box is so unique, it combines your love of reading with the joy opening presents.

    The gifts truly bring the story to life and perfectly match what’s happening in the story. For example-the main character might have gotten a bracelet from her best friend in the story. And then you get that bracelet as a gift! It’s so fun because it’s an immersive experience.
