Two New York artists’ tumultuous friendship gets turned on its head when one of them goes missing and the other may be to blame. A riveting debut novel for readers of Bunny, Luckiest Girl Alive, and “Who Is the Bad Art Friend?”

Anna had never met anyone like Willow. Entering art school with lofty ideas about Art and her role in it, Anna was wholly unprepared for someone as mysterious, moody—and cool—as Willow. Here was Anna’s muse and collaborator all in one, ready to bring her in on Art’s great secrets.

Now, five years later, Anna is weary. Where art school was boundless creativity and collaboration, the New York art scene is all about survival. Worse: Willow’s true nature as a muse only to herself has become nakedly apparent, as has her cruelty.

So the mugging Anna has staged for Willow this morning? It’s supposed to send Willow running back to her true friend. The knife is supposed to be a mirror in which this ‘artist’ can finally see the monster she’s become. It’s supposed to give Anna her power back.

But this morning isn’t just any Tuesday. It’s September 11, 2001. And as the city reels from the seismic events of that day, Willow never returns home. Anna keeps quiet about the prank and her growing panic that she’s to blame for Willow’s disappearance. But as the hours and days tick by, Anna begins to question whether she’s the mastermind she thought she was, or the pawn.

Alternating between the friends’ art school tenure and their lives in 2001 New York, Tell Them You Lied reveals how difficult the search for answers is when you’d rather have anything but the truth.
