The Siren

You are aboard a small boat on the calm blue lake after a long week of working, with the afternoon sun shining among white clouds. Your free living, risk taker best friend guides the wheel with a wide grin as the wind blows through their hair.
The boat comes to a steady stop. "What did I tell you?" They ask stepping to the edge of the boat arms outstretched, gesturing to the lake and the partly shaded sun high in the sky. "Beautiful as the Bahamas! Miles from traffic and busy people running around like chickens with their heads cut off."
You simply smile and nod in agreement.
Your partner gives you a sideways glance. "You've gotta get your mind off the week... water looks perfect, doesn't it?"
"Yeah... I guess." You reply looking into the water, noting the seaweed flowing in the subtle waves. "I thought we were going to fish?"
Your partner takes a step towards you, "Yeah, but we don't need the poles."
Before you can reply you feel their shoulder slam into you, losing your balance you flip over the edge of the boat, your partner letting out a subtle laugh. Knowing you're about to hit the water, you take a breath, before the cold embrace of the lake hits your chest. You sink a few feet below the water. All goes quiet, the water is the perfect temperature. You feel the seaweed against your feet. It's quite peaceful for a moment. You turn your head however, and you are confronted by the pale face of a girl in the water, seemingly lifeless with a blank stare, floating amidst the water around you. Long strands of hair waving among the seaweed.
After the initial shock, and realizing she must have drowned herself as a way of suicide. You look closer for a moment, knowing you'll need to go up for air very soon. The eyes black as onyx, seem to come back to life. Must be your eyes playing tricks on you… you could swear you saw one of her fingertips twitch… is it possible she's still alive? But as you panic, horror strikes you, as her lips curl into a terrifying smile, revealing two rows of sharp teeth each filed to a point… this thing is not human.
You push through the water as swiftly as possible, feeling the weight of every gallon of water sitting above you, and the weeds below your feet claw at your ankles as you struggle to get to the surface of the lake. Just when you feel you can't go without a breath any longer, your head pierces through the surface of the water and you throw your head back to take a breath. Your partner is still on the boat laughing. You scramble to the boat, pulling your body over the side and flopping down in the boat, still gasping for air.
“Oh come on, it couldn't have been that bad!” they say preparing to jump into the water.
“Don't!” You yell as firmly as possible with a slight quiver in your voice. “There's a shark in the water!”
They stop, and look at you quizzically. “There are no sharks in the lake. You probably saw a trout.” they reply continuing to prepare to jump in the lake.
You pull yourself up on weak muscles, still dripping wet, to grab their shoulder to keep them from going in the water. “I'm not kidding! There's something in there! And it's big. We need to go back!”
Your partner, is now growing tired of the game. “There's nothing in the lake except fish and a couple beer bottles.”
Just as the words leave his mouth, the boat is hit in the side by a heavy force, enough to rock the boat and make both of you stumble trying to keep your balance. Your partner is now beginning to worry, and perhaps believe your story. “What was that?”
The boat rocks again and this time you catch a glimpse of the horrifying grin of the girl with shark like teeth, before she dives back in the water.
Your partner becomes more urgent. “What was that?!”
Without answering you run to the head of the boat, but you are thrown to the flooring from another hit taken by the monster trying to take down your boat. You get back up and grab the wheel, start the motor and hit full speed straight ahead, no sense of direction except away from the creature. You look back to make sure your partner is still in the boat, who is still looking back, then to you in terror. Then you notice the water behind you beginning to part, and not from the boat. The creature is chasing you, and not far behind.
You make sure the boat is going as fast as possible, then turn to your partner. “Grab the flare gun and shoot it!”
They break from the trance and grab the flare gun from a box in storage on the boat. You look ahead to continue steering. You hear the sound of the flare gun fire, and turn to see it hit the girl in the head as she came up to dive back down. There's a slight yelp, before she dives down below the surface and the water becomes still except for the current behind the boat.
You and your partner exchange glances before looking ahead again. Neither of you say a word for the rest of the journey home. You make it back to the docks without further mishap. When they ask why you were back so early, you simply say that you forgot your phone, as you pat your pocket feeling the indentation of your phone safely tucked away.
And not another word was said of the shark like creature in the lake. No one would believe you anyway. Nevertheless, you nor your partner will ever look at a body of water the same.
