The Other Mistress — Shanora Williams

The New York Times and USA Today bestselling author weaves an insidiously sexy twist-filled novel of domestic suspense about the increasingly dangerous alliance between a betrayed wife and the Other Mistress. Will appeal to fans of Liv Constantine, Tarryn Fisher, and Caroline Kepnes.
 
Adira Smith-Cortez knows how to turn around a troubled past. Now she's a self-made multi-millionaire who takes exquisite care of herself and her only true love: her husband, Gabriel. Adira has it all -- except the answer to one tormenting question: why is attentive, affectionate Gabriel cheating on her -- with not just one, but two women. There's sexy Jocelyn, a club owner. And then there's Julianna, a celebrity makeup artist he's even crazier about. In a tricky twist, vengeful Jocelyn offers Adira the perfect plan to get her straying spouse back . . .
 
It sounds simple: Adira will befriend Julianna through a fake identity, play on her and Gabriel's vulnerabilities and cause them to split up permanently. Determined to reclaim her happiness, Adira won't -- can't -- stop to think what could possibly go wrong . . .
 
Until too many of Gabriel's lies start adding up to a disquieting truth. Until Julianna discovers who Adira really is -- and Jocelyn pushes Adira to ever-more-unthinkable extremes. With her world collapsing and shattering memories tearing her apart, how far will Adira's obsession take her -- and how much of herself is she willing to lose in the process . . .  
 
“A shocking, sensual thriller.”
