Penguin presents the audiobook edition of The Sacrifice Box by Martin Stewart, read by Christos Lawton.
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 for ever. 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, a series of strange and terrifying events take place. Someone broke the rules, and now everyone has to pay.
But how much are they willing to sacrifice?
Fifteen-year-old Wulliam is dreading taking up his family's mantle of Riverkeep, tending the river and fishing corpses from its treacherous waters. But then everything changes. One night his father is possessed by a dark spirit, and Wull hears that a cure lurks deep within the great sea-beast known as the mormorach. He realizes he must go on an epic journey downriver to find it - or lose Pappa forever.
