REVENGE CAN BE ECSTASY.

Irina Ismaylova is a sexual assassin, luring men and women to her bed...and their death.  From St. Petersburg to Paris, she kills not for money or for pleasure, but under orders from the Russian mafioso who holds her in thrall.  Desperate to buy back what is left of her shattered life, Irina must carry out
one last mission....

Cate Cuevas is a special agent in Houston's FBI office.  Devastated by her husband's death--and his betrayal--she has plunged into the most dangerous
assignment of her career.  But to succeed, she must form a secret and profoundly intimate alliance with the enemy: Irina Ismaylova.

Two women.  One a cop.  The other a killer.  

For these two there is no right, no wrong, no rules.  

Only the truth...and terror.

From Booklist

Two women, both undercover agents of sorts, find their fates inextricably enmeshed. Irina Ismaylova is an assassin for ruthless Russian crime boss Sergei Krupatin, who controls her by holding her young daughter hostage. Cate Cuevas is a DEA agent who has lost her agent husband in an undercover operation that was botched because of the husband's philandering. Cate is assigned to accompany one of Krupatin's trusted lieutenants (who has been converted into a double agent by the DEA) to a mysterious meeting in Houston. The plan is to get Cate close to Krupatin and then arrest or kill him. Irina will also be there, assigned to eliminate Krupatin's key competitors. Of course, nothing is as it seems, and the initial plans quickly disintegrate into a multicornered cat-and-mouse game. The novel is seriously overplotted; there are simply too many twists to maintain credibility. But the relationship that develops between the two women redeems the book's excesses. Recommended with reservations. George Needham

From Kirkus Reviews

With more women in the global workforce every year, it seems inevitable that at least a few will become hired guns. Here, old pro Lindsey (An Absence of Light, 1994, etc.) spins the implausible but nuanced and suspenseful tale of one such working mother. Sergei Krupatin, the vicious chieftain of a world-class criminal syndicate connected to Russia's mafia, employs Irina Ismaylova as an itinerant assassin. Although trained as an art restorer, the drop-dead blond beauty is obliged to retain her odd job because Sergei (a crafty, up-from-the-ranks Chechen) has long held her (and his) young daughter as a hostage. After completing a twofer assignment in St. Petersburg, Irina learns that she's to be Sergei's go-between in setting up a summit conference in Houston with Chinese and Sicilian drug lords; the lethal Irina also learns that she's expected to kill both men, Wei Tsaing and Carlo Bontate. Meanwhile, offshore intelligence sources have alerted the FBI to the Texas meet, which is to be attended by Valentin Stepanov, Sergei's man in America. The feds have turned Valentin and plan to use him to insinuate another undercover agent into his master's inner circle--Catherine Cuevas (a.k.a. Cate), the comely widow of a philandering DEA operative. Bearing a transceiver implant in her right arm, Cate soon encounters and bonds with Irina, who has made a side deal with Carlo to betray Sergei in return for help in recovering her child. The mafioso instructs Irina to follow through on dispatching Wei--and she does so with considerable flair in the course of a three-way group grope with Cate. But the girls must still settle with Sergei, who's gone to ground. Only one of the treacherous trio survives the final confrontation for a tear- jerking postlude. Equal opportunity is a dominant if implicit theme of this violent, broody, overlong international thriller, the only moral of which seems to be that sex kills.
