House of Secrets: The Collision of Worlds (Vol. 3)

The conclusion to the New York Times bestselling trilogy, which J.K. Rowling called "a dizzying rollercoaster of adventure."

After their last adventure through the world of books, Cordelia, Brendan, and Eleanor Walker thought their lives would finally return to normal. But things weren't so calm. Especially after Gordo Jagger decided to show up in the San Francisco Bay Area—and put them in serious danger!

With the police closing in, the brothers must figure out how to save the giant. But as other mystical creatures begin to appear across America, it becomes clear that Denver Kristoff's characters are invading the real world.

The Walkers will have to return to the universe created by the writer to prevent the collision of the two worlds and avoid the destruction of their home.

The only way out for the brothers is to find the three Protectors of Worlds hidden in Kristoff's books.

Together, the objects become the only thing that can separate the two worlds once and for all.
