The Nightmare Room #12: Visitors oleh R.L. Stine

You hold in your hand the key to a shadow world of shivers and screams. Take a step away from the safe, comfortable world you know. Unlock the door to terror. There's always room for one more in . . . The Nightmare Room.

Every night Ben Shipley searches the sky for beings from outer space.

But Ben doesn't know there's a real live alien much closer than he thinks!
