"Thrilling, intense, with pulse-pounding chills . . . Everything you could want in a series." --Soman Chainani, New York Times bestselling author of The School for Good and Evil

New York Times bestselling authors Ally Condie and Brendan Reichs co-author another edge-of-your-seat adventure in this darkly suspenseful middle grade series.

Nico, Opal, Tyler, Emma, and Logan survived their worst fears come to life, and saved their tiny Pacific Northwest town of Timbers from a monstrous figment invasion. Now they just want to keep their heads down, enjoy Halloween, and explore the secrets of their mysterious houseboat clubhouse. And also figure out their new Torchbearer responsibilities as keepers of the Darkdeep, an ancient whirlpool hidden in Still Cove that can make both dreams and nightmares into reality.

But when a dangerous new breed of figments starts appearing on their own, and the very environment around them begins to spiral out of control, the friends realize they have no idea what they are doing-or how they're supposed to restrain the Darkdeep. They must uncover the pool's origins, as well as those of the freaky Thing in a Jar, a seemingly lifeless green creature Opal believes is communicating with her. To make matters worse, a trashy YouTube series has rolled into town intent on finding the Beast, the legendary local sea monster suddenly stirring up the countryside.

As threats rapidly close in around them, the friends must fight to protect their secrets, defeat new enemies, and save Timbers and all that they love.

Told from alternating points of view, this chilling sequel from bestselling duo Ally Condie and Brendan Reichs will once again have readers sleeping with the lights on.
