Perfect Family by Pam Lewis

The Carteret's vacation home on Lake Aral in Vermont has been in the family for generations. When William's youngest sister, Pony, calls him and says that she needs to see him up at the lake house he agrees to meet her there because they've always been close. Pony has a baby son, Andrew, and has always been a free spirit, never revealing to anyone who Andrew's father is. When Pony is found dead at the bottom of the lake after William leaves, all the family's problems and secrets come to the surface. William isn't particularly close with his other sisters, Tinker and Mira, and has always felt out of place with his father, Jasper. Their mother, Olivia, was loving towards William, but she died a few years ago. William feels he must find out what happened to Pony especially when it seems as if she might have been murdered. What William uncovers will change the family forever... While some reviews have billed Perfect Family as literary, I would call it a character-centered page turner.
