for Shark Attack! by Jake Maddox
"Ever since he arrived at his family's rented summer house, Brendan has been hearing horror stories from all of the locals about sharks in the water. His new friend and surfing partner, Alex, swears the stories aren't true, but Brendan can't shake his fear. Then, one day, when Alex and Brendan are surfing off the coast, Brendan's shark nightmare comes true in a horrible way."
