The Vicious Circle — Katherine St. John

For fans of We Were Never Here and Nine Perfect Strangers, a twisty, escapist suspense about a mysterious wellness retreat center harboring violent secrets.

A perfect paradise? Or a perfect nightmare?

On a river deep in the Mexican jungle stands the colossal villa Xanadu, a wellness center that's home to The Mandala, an ardent spiritual group devoted to self-help guru Paul Bentzen and his enigmatic wife Kali. But when, mysteriously, Paul suddenly dies, his entire estate -- including Xanadu -- is left to his estranged niece Sveta, a former model living in New York City.

Shocked and confused, Sveta travels to Mexico to pay her respects. At first, Xanadu seems like a secluded paradise with its tumbling gardens, beautiful people, transcendent vibe, and mesmerizing de-facto leader Kali. But soon the mystical façade wears thin, revealing a group of brainwashed members drunk on false promises of an impossible utopia and a disturbing, dangerous belief system -- and leader -- guiding them.

As the sinister forces surrounding Sveta become apparent, she realizes, too late, she can't escape. Frantic and terrified, she discovers her only hope for survival is to put her confidence in the very person she trusts the least.
