Eager to know what the moms, Penny, Carrie, and Bess, did in Summer 16 in the We Were Liars sequel novel? Although the latest psychological thriller follows Cadence’s journey to recover her memories after a tragic accident, it also subtly highlights disturbing past her mom and aunts have kept from their own Summer 16. The past has shaped their current lives and has left emotional scars, which continue to bother them. The sequel novel, however, has revealed what happened to the moms.
So, here are all the details.

Here’s what moms did when they were 16 in We Were Liars
The series showcases that Penny, Carrie, and Bess’ relationship over the years has been strained. They usually compete against each other to be in their father’s good books to gain his preference and inheritance. However, the Sinclair daughters’ hatred for each other stems from what happened when they were 16. This particular event has made their bond even worse in the present day.
Although the series doesn’t reveal the moms’ summer 16, We Were Liars’ prequel novel, Family of Liars, does. The book chronicled Carrie’s love story with a guy named Pfeff. They genuinely appeared to love and care for one another, but there have always been challenges in their bond. Their relationship takes a turn for the worse when Carrie discovers that her beau has cheated on her with Penny. This worsened the sisters’ dynamic.
Later, Bess reveals to Carrie that Pfeff had died. She explained that it was an act of self-defense while trying to save Penny, who had been assaulted by him. According to Bess, he was struck on the head with a loose board from the pier, which caused his death. Nevertheless, the Bess narrated story wasn’t the truth. It wasn’t Bess who killed him, but it was Carrie who did after being jealous of Pffef’s relationship with Penny.
At the time, the three sisters set aside their grudges and got rid of his body. They created a fake narrative about Pffef being drowned in the water and being eaten by the sharks. This tragic incident is known only to the sisters. As a result, they believe that when they lost their children, Johnny and Mirren, it was a punishment from God for their heinous crime.
