Jack reached for his magic library card. When hefelt its tingly warmth, he knew that amazingadventures lay ahead.

"Let's go," he said.

He turned on his flashlight.

"Hey, the darkness is like a mask," said Annie.

"Yeah," said Jack. "It hides the day, but it brings outyour courage."They came out of the woods.

Jack saw their house in the distance. It lookedwarm and cozy.

The porch light glowed. The moon shone overhead.

"Home," he whispered. "Home," said Annie.

She started running. Jack took off after her, runningto the place that they both loved the best.
