ONCE TWO SISTERS~When her sister goes missing, Zoe assumes it's just another one of her estranged sibling's stunts--but the danger is all too real.

Zoe Hallett and her sister, Ava, are the precocious offspring of two pioneering scientists, but the sisters have been estranged for years. When Zoe reads a news story about Ava's mysterious disappearance, she assumes it's just another of her sister's twisted fictions, designed to blame Zoe and destroy the peaceful life she's created with her husband and beautiful stepdaughter in Houston. But Zoe's email is hacked to send threatening messages to Ava--and a more sinister picture begins to emerge.

 As her sister's life hangs in the balance, Zoe draws on hidden reserves of strength and hope to save the sister she never thought she loved.

YOU CAN NEVER TELL~Framed for embezzlement by her best friend Aimee, museum curator Kacy Tremain and her husband Michael move from New Jersey to a charming Texas suburb to escape their past. Kacy quickly makes new friends–preppy, inscrutable Elizabeth, chatty yet evasive Rahmia, and red-headed, unapologetic Lena. But good friends aren’t always what they seem.

As she navigates the unexpectedly cutthroat social scene of her new town, Kacy begins to receive taunting postcards–and worse, discovers cameras hidden in the wall of her home. Lena and her husband, Brady, reassure her that the cameras are just relics of the paranoid previous homeowner . Once the cameras are removed and Kacy’s fears are quelled, Kacy and Michael make the happy discovery that they are going to be new parents.

Months after the birth of their daughter, Michael accidentally makes a shocking discovery about Brady’s past. And when Lena suddenly goes missing, Kacy and Michael begin to uncover the truth about their neighbors–and it’s more terrible than anyone could have imagined.

Interlaced with transcripts of a chilling “true crime” podcast that follow the tangled threads of the drama, You Can Never Tell is a taut and complex psychological thriller that never lets up until its breathless conclusion.

“A thrilling roller coaster ride through the dark, dangerous underbelly of suburbia. I loved the tension between these picture-perfect housewives and the twisted secrets they keep tucked out of sight.”
—Jody Gehrman, author of The Girls Weekend

Perfect for fans of Melanie Golding and Joshilyn Jackson, You Can Never Tell, Sarah Warburton’s chilling thriller inspired by the Moors Murders explores the twisted side of suburbia.
