Diego and his friends must face the legendary Mexican boogeyman, El Cucuy, in this fast-paced, action-packed middle grade horror that’s Rick Riordan meets R. L. Stine, the sequel to Lost on Doll Island.

Stay awake. Stay alive.

After going head-to-head with a demonic doll, life for Diego now is surprisingly good. He’s settled into Mexico City, he’s joining clubs at school, and he, Jandro, and Itzel are tighter than ever. Better yet, he hasn’t dreamt of one doll since he left La Isla de las Muñecas. Though Tomas remains under Itzel’s watchful eye, “living” in her house, things finally feel normal for the three amigos.

Until kids start mysteriously falling asleep…and never waking up.

When Diego hears rumors of a boogeyman with the power to enter children’s dreams and steal their souls, he knows there’s a connection between the sleeping illness that has fallen over his school and this monster.

But beware of El Cucuy, because once you enter his domain of dreams, he’ll do everything in his power to make sure that you don’t…wake…up.
