Pretty Little Lion by Suleikha Snyder

The rules of undercover work are simple:
Never fall for your mark.
Never let down your guard.
Never give your heart away.

Lion shifter and Third Shift co-founder Elijah Richter is on a mission: seduce arms dealer Mirko Aston’s gorgeous girlfriend, use her as an entry point to the organization, and discover what the global terrorist is planning. It should be simple.

Then he meets Meghna Saxena-Saunders—influencer, celebutante, ex-wife to a handsome Hollywood hotshot, and a highly trained apsara assassin—and all his plans are blown out of the water.

Meghna immediately clocks the mysterious stranger watching her at a VIP party and decides she’s curious enough to play along. She and Elijah fall headfirst into their lusty bed of lies, but when their steamy morning-after is interrupted by one of Aston’s goons, both of their missions are thrown into jeopardy. Now Meghna must team up with Third Shift to cover her tracks, discover the truth, and resist falling for a man who thrills her to her core…before it’s too late.
