The Sacrifice Box by Martin Stewart is a YA horror book (whelp) with its fair share of gruesome murderous ehm… things? animals? corpses? and gore, but also with a fun cast of teens!
Sep, Arkle, Mack, Lamb and Hadley: five friends thrown together one hot, sultry summer. When they discover an ancient stone box hidden in the forest, they decide to each make a sacrifice: something special to them, committed to the box forever. And they make a pact: they will never return to the box at night; they’ll never visit it alone; and they’ll never take back their offerings.
Four years later, the gang has drifted apart. Then a series of strange and terrifying events take place, and Sep and his friends understand that one of them has broken the pact.
As their sacrifices haunt them with increased violence and hunger, they realize that they are not the first children to have found the box in their town’s history. And ultimately, the box may want the greatest sacrifice of all: one of them.
