Pizza Hut will once again be treating voracious readers this summer.

The Hut is calling on parents to enroll their children in its famed BOOK IT! program, announcing April 23 that its free reading incentive program is returning for the summer.

"SUMMER OF STORIES IS BACK! 📚🍕," the Plano, Texas based pizza restaurant chain said in an Instagram post.

Kids who've met their monthly reading goal can redeem a free, one-topping personal pan pizza by presenting their digital Reading Award Certificate at any participating Pizza Hut location.

"Enrollment opens May 1st—get ready to turn reading time into pizza time! This summer, keep your kids’ reading, learning, and loving books… all while earning FREE pizza," Pizza Hut added.
