Vermont has always been Phil's favorite place in the whole world. From maple syrup farms, to shimmering Lake Champlain, to Ben & Jerry's Ice Cream, what's not to love? So when Phil's family heads to Burlington for the Fourth, he is thrilled! That is, until the twins, Fia and James, tell him about all the people who have vanished in the lake . . . and the terrifying beast said to lurk below its surface.

Phil isn't about to let some silly old legend ruin his summer--or his ice cream. But when a creature in the water nearly attacks him, Phil and his friends will have to team up to take down the lake beast once and for all--unless it gets them first!
