Verity's Game by Jennifer Giacalone

A lovers-to-enemies lesbian romantic thriller which proves killing is hard, but falling in love might be a death sentence. Two elite, undercover, rival assassins are drawn to each other after meeting at a nightclub to unknowingly carry out a hit on the same man. For lone wolf American assassin Verity, their connection is so intense she thinks she might want to risk falling for gorgeous Mexican translator Reina. Too bad Reina's next contract is to kill Verity—a woman Reina is so attracted to it scares her to her core. In this fast-paced scramble through the dark clubs, cafes, and gleaming art galleries of Mexico City, their lethal game becomes about far more than just saving their lives.
