Elemental Sisters by Douglas Green

A husband, wife, four newborn daughters and the nanny, Rina, were traveling through space on a family trip to the wife, Eva's, home planet, Creed. They were traveling to Creed to celebrate the birth of their four beautiful daughters: Khaleesi, Fiona, Katana and Chi-Chi. Eva and the father, John, were geneticists by trade. Eva asked her husband if he could plot a faster course home. He plotted the course through a wormhole because it would cut three days off their five-day trip to Eva's home planet, Creed. She paced the deck, eager to see her mother, whom she hadn't seen in ten years. She wanted to celebrate the birth of her four daughters with her mother. As the wormhole opened, John guided the small cruiser in at a fast rate of speed without slowing down. The ship's impact alert roared as John switched the ship to manual control. Before he could see what was on a collision course with the ship, something large hit the ship, tearing a great hole in the side. The ship spun out of control.
