How can i fix this shooting code in a 2D plane?

At the moment, this code fires towards the camera for some, unknown reason. What is the fix and explanation of why this is happening?

     GameObject firedSpell = Instantiate(spell[currentSpell], new 
     Vector3(transform.position.x, transform.position.y, transform.position.z), 
     Quaternion.identity) as GameObject;

     firedSpell.GetComponent<Rigidbody2D>().gravityScale = 0.0f;

     Vector2 target = Camera.main.ScreenToWorldPoint(new Vector2(Input.mousePosition.x, Input.mousePosition.y));
     Vector2 myPos = new Vector2(transform.position.x, transform.position.y + 1);
     Vector2 direction = target - myPos;
     direction.Normalize();
     firedSpell.GetComponent<Rigidbody2D>().velocity = direction * 15;
