A door appears where no door should be and four friends are the only ones who see it.
Milo Reyes has always felt most at home in the school library. So when a faint outline of a door appears on the back wall - one that glows at the edges and disappears when the light changes - he knows he isn't imagining it. He knows because when he finally tells his friends Jada, Owen, and Lila, they see it too.
Together, the four of them step through and into the Whispering Library: a hidden world of talking books, secret rules, and stories that have been waiting a very long time to be heard. But something is wrong. An important story has gone missing, and without it, the doorway is beginning to close.
To save the library - and find their way home - Milo and his friends must learn to listen, work together, and trust themselves before the door disappears forever.
The Door That Wasn't There Yesterday is the first book in The Hidden Doorway Club series: a cozy chapter book mystery about curiosity, courage, and the stories that find us when we're brave enough to look.
Perfect for fans of The Magic Tree House, Geronimo Stilton, and A to Z Mysteries. Great for independent readers and read-alouds alike. For ages 7-9.
