Wholesale Skinny-Dipping at Monster Lake by Bill Wallace

[Aladdin] Kent doesn't believe in monsters. But he knows he saw two gleaming yellow eyes beneath the surface of Cedar Lake when he and his buddies were camping at the lake. When he sneaks out alone a few nights later to investigate, the eyes return -- and they seem to be following him. Kent and his friends are determined to solve the mystery of the Cedar Lake monster. But what they discover one dark summer night is just as surprising as a monster -- and just as dangerous.
